I'm not 100% sure I'll start him but even if I do start him, I won't necessarily "cheer" for him.
I've learned awhile ago that you have to take your homerism and/or favoritism out of fantasy football if you want to win. In some some leagues you have more options to select your players like salary-cap leagues.
You'd be a fool to not start the best player just because you don't like them.
I even like Peyton...I just don't think he's going to do as well as we were all accustomed to seeing from him...I think it will take time for him to achieve his usual form...
