Wow, that was quite the response Shrimp. And interesting too. Mine will probably end up being just as long, I love talking about this stuff.
Here's my routine.
My week starts Sunday night during the late game now. I used to start on Tuesday or Wednesday, but I missed out on too many values. I'd always be kicking myself saying Oh Man, I could have gotten 2? etc. Lines come out around 8 or 8:30 at Olympic and I try to get a look at them as soon as possible. These early early lines can be quite different than what they will be a day later and you can often save yourself a valuable half point or more. I may put in a bet right there, maybe once every second week I spot something right there and hit it. Of course the downfall of putting something in this early is you can't fully hash it out. And on occasion I'll actually get an inferior line if it moves the opposite direction that I think it will go. But I've had real success with these early plays regardless.
Monday of course I will study that night's game. I've already got the basis of my research done thru the week, so usually there's not too much thought or work required.
Tuesday evening I read up on what happened on the weekend, go over boxscores, and see if anything stands out. I've got a statistical spreadsheet system that I enter all of the previous week's scores into. This system gives me a basis to start with, potential plays if everything else pans out. I've got a book (Carib) that offers 2% juice on Tuesdays, so if I found something on Sunday that wasn't urgent, or if I can find something on Tuesday that looks good right off the bat I will take advantage of the reduced juice. I usually put in at least one bet on Tuesday. Saves a couple of units over the course of the year just putting in bets on reduced juice days at the various books.
Wednesday I take a break usually and don't do anything too brain straining. Gotta have a bit of a break from it or I don't see things clearly.
Thursday I start to get serious about it. I check out teams rushing offence & defence numbers, passing offence & defence numbers, etc. Mostly all numbers stuff to start to dig for the not-obvious plays. I keep track of any mismatches I can find. Start tracking how the lines have moved since Sunday at my books. Probably 3-4 hours at least of math-intensive (mostly) study. Also start looking for letdown/overlook situations, analyzing each team's schedule, and like Shrimp mentioned, I like to compare the current opponent to recent ones for each team. A big part of handicapping I find is finding situations where a team has played one type of team for 3-4 weeks in a row and suddenly runs into a polar opposite. Situations like this are a lot more important than sheer statistics.
By Friday I have some idea of what I will play on the weekend. I start entering my contests. I am in a LOT of contests and I like to get them out of the way early. REALLY screws me up if it's Sunday morning and I haven't gotten to this yet! I enter different picks in every contest...not just my best bets, but a variety of picks, often times opposite sides of the same game in different contests. It's funny, I don't take these contests all that seriously, I'm very casual about what I take...but it's an important part of my handicapping now. When it's over I look at my contest sheet and I start to see teams that I have taken repeatedly without making a conscious effort at doing so. This process gets my brain thinking in a different way, away from the numbers. I can't really explain it, but it's vital to how I work now. I also start to track what is coming up in the consensus at Big Guy, the Hilton Contest, etc, to get an idea of what other people (sharp and not-so-sharp) are thinking. This can be useful for avoiding a few public picks, which lose more often than win. Friday night I will put in a couple more plays (again, some at reduced juice, 5% at another of my books). Will hold back putting in dogs or unders if I feel I can get a better line Sunday.
Saturday is another lighter day. By this point I have usually looked at each game every way possible, backwards, forwards and upside down. Will check out weather reports, finish the contests if they aren't done yet, and get to bed early if I can (which would be anything before 2am).
Sunday, I'm usually up around 10 or so. Got about 7 or 8 browsers open (one for each book + Madjacks + a couple other sites)...spreadsheet, papers everywhere...TV on the pregame shows. By this point I know what I want and I'm usually just hitting refresh on all my browsers waiting for the number I want to come up on whatever it is I am betting.
Of course I watch all the games (man I love Sunday Ticket!). Will try to hit some halftime middles or whatever I can. By 7:30pm I am pretty much drained. Get in a bet on the 8:30 if I'm playing it, get those early lines. By halftime of the Sunday night game I've usually passed out on the couch. Hopefully UP money for the day.
=============================================
So that's my week.
Things I believe in, in no particular order:
*Comparisons of recent opponents to the current one.
*Opposing the public.
*Betting more dogs than favorites whenever possible.
*Statistical mismatches.
*Letdown/overlook/bounceback situations. Players are human beings and are prone to overconfidence, dejection, embarassment, and everything else the rest of us are. If you go by numbers only you never spot this.
*Systems plays.
*Discipline. Being able to let a Sunday night or Monday night game go by without a bet on it if I don't truly see value. Not getting desperate when I've had a bad day, or getting over-confident and careless when I've had a good day.
Things I don't believe in, or try to ignore:
*Long-term head-to-head trends. Knowing Team A beat Team B 18 times in a row in the 1980's is of no value to me...has no bearing on this week's game as I see it. I ignore almost any trend that goes back more than 3 years if it is team-specific or this-team-vs-that-team specific.
*Betting on a game because "they're due", or because "they can't win/lose X number of games in a row (trust me, they can).
*Betting on a team because it's a "must win" game for them. I've found in the past "must win" teams lose so often, it's almost a system to go against a team in this position. If a team is in a "must win" situation, that usually means they haven't gotten the job done adequately up to now...so why would they suddenly get their act together today? Plus the line is usually inflated against them as most other people are also thinking they "must win"
*Revenge. I really dislike this angle. Saying a team will be mad because they lost to them last year in Week 4 and they will remember it etc etc. It's all bunk as I see it.
*Betting on teams because of non-related events. IE. Sunday all the dogs covered, so it's a dog's week....or Sunday all the dogs covered, so the favorite should win tonight to balance things out. Also includes things like "The Browns will win this week because their owner died", "The New York teams will win this week because 9/11 happened one year ago this week", etc. Forget that stuff.
