I don't like Lance Moore, but matchup wise he has a chance against TB. I've seen Tampa get burned multiple times this year. Bess and Amendola are pretty much the same thing.. solid PPR numbers. You are right about Williams being the best longterm option. I would definitely roll with at least one of Bess and Amendola for some consistency. Then it depends on how your team stands imo. Where are you in the standings? How are the rosters of the people you are playing these next two weeks? Can you afford to take a chance with Williams or Moore or do you need more consistency with Amendola and Bess? You'll have to watch the injury report, but without knowing your situation I like Bess/Amendola and Mike Williams. I really like Mike Williams for the longterm. It might take a few more weeks, but Freeman throws it up to him pretty often from what I've seen and he is very talented.
