It's not bad. RBs are a little thin, though, so you'll most likely be flexing a receiver all year. I always prefer the RB flex, but the only league championship I won last year was with deep receivers and thin RBs. Granted, it was my least successful team (the other two were top seeds), but I'll take the pinnacle any way I get there.
yea, I like RBs at the flex spot too.. but the options were bad.. I thought Nicks was the BPA
