Hmm, Freeman I guess. Fitzpatrick I keep thinking is gonna breakout again, but he hasn't. Plus Denver has a pretty strong pass rush.
Freeman looked pretty good at the end of the Cowboys game, so maybe there is more hope he can do something against Carolina.
The other one though is a toss up...
Thomas probably won't play much, since they are probably gonna be behind and Reggie will be in even more than usual.
Walter hasn't done much at all, but at least the Colts suck.
Are those really the only players available for your flex spot? I guess I'd probably go Walter, Houston is more likely to still be passing, than Miami to be running, and at least Walter has scored a few times this year.
