Note: As I release this play around 1 A.M. Eastern on Wednesday, there are more 3's than 3 1/2's both in Vegas and offshore. In either case, I would absolutely buy down to -2 1/2 or 3. And if for some reason this line moves back up and you're saddled with -4 - even after shopping for the best price - go ahead and buy down the half-point to -3 1/2 on the Panthers.
