BOWL FAVORITES/UNDERDOGS
We've been keeping a close watch on bowl underdogs for the past few decades, and with good reason. For the most part, the bowl "short" has been a positive pointspread proposition, moreso at the higher pointspreads. Dogs getting 7 or more have been solid pointspreads. for most of the past 29 years. Still, it's worth noting that despite cumulative positive marks compiled by the underdogs (especially the bigger dogs), such patterns remain cyclical, as we've said many times before, that no technical trend or angle is ever etched in granite, and to blindly follow any past trend or pattern is not advised. Indeed, There have been some extended stretches of time when bowl underdogs enjoyed little success vs. the spread. As always, proceed with caution.
Still, common sense mandates that we acknowledge historical performance. Along that "cyclical" theme, please note that bowl underdogs fared well between 1974-87, recording a 112-77 spread mark during that span. They continued on the plus side until 1992, when a noticeable shift in bowl results began. A period of favorite-slanted postseason results commenced, the chalk rolling up a 62-44 edge over the next six bowl seasons. Dogs, however, have returned with a lot of bite since 1998, as underlined by a 74-48 mark vs. the line the past five campaigns.
Such numbers invite further refinement. And, upon inspection, please note that bowl favorites have generally come up short in pre-New Year's bowls. Indeed, far short the past three seasons (dogs 37-15 vs. line in those games since 2000, including 13-6 last year). And that makes some sense. Keep in mind that polls and rankings aren't usually considerations in such games. Some of those early-bowl favorites tend to be disappointed "bowlers" after falling short of often-loftier preseason goals, while underdogs, some often thrilled merely with the opportunity to play in a bowl, approach the contest with a bit more gusto. The early bowls are often played in front of less-than-capacity crowds, making the entire scenario a far different one than experienced during the regular season. The dynamics are often much different. Certain pre-New Year's bowls have featured unmistakable dog success in recent years, most notably the Sun (dog 11-1-2 last 14), Peach (8-2 last 11; one pick 'em) and Independence (11-4 last 15) in recent years. Note some scheduling quirks this year, however, as a few traditional "early" bowls, such as the Peach and Humanitarian, are being played after New Year's Day this year. Go figure!
On the other hand, New Year's (and after) bowls have been favorite-dominated for several seasons. That "chalk trend" has generally followed an interesting parallel with the NFL, which has often seen its post-wildcard trend favorites perform well since the early '90s. And the rationale makes sense. Those New Year's bowl favorites usually represent the "cream" of the college football crop, often well-equipped offensively and well-motivated with rankings, and, sometimes, national titles on the line, to extend a margin, not adverse to "pouring it on" and leaving little chance for a desperate comeback by the trailing squad, thus lessening the chance at any resulting "backdoor" cover possibilities. Despite the aforementioned success of underdogs in pre-New Year's bowls the past three years, the "chalk" stands 15-8 against the line in New Year's or later bowls that span. Note that in "national title" Bowl Alliance or BCS games since the 1995 season, only twice has a contest been decided by fewer than 17 points (Tennessee's Fiesta Bowl win over Florida State after the '98 campaign and Ohio State's OT thriller vs. Miami-Florida last January).
If one thing has remained constant for the past 29 years, it has been the success of the biggest bowl underdogs dogs, those getting 7 points or more. The "short" has recorded a 92-60 (61%) spread mark in bowls since '74 with spreads of 7 or more, with the biggest dogs (those getting 14 points or more) covering 16 of 24 chances.
