I layed -420 on Gardner this morning. Felt it was a solid play considering ESPN Hometown, plus his opponent is a substitute. The 2nd Sub so far for this card set to fight him. I opened my number much higher, but was beat to putting it up this week because I was working on all the other bouts that are going up now, plus K-1, plus Bushido, plus everything else that will take most shops about 20 minutes to copy.
Good luck on Gardner. I think its the right side, but I think the number is high enough now.
