drafting a defense early is a mistake, i wouldn't touch the buffalo d even close to where they're going, even though i do believe they could be the highest-scoring d for the second straight year.
i love sammy as a sleeper. injuries are my only concern. if i really want a guy like that, ill usually take him at his ADP - # of teams in the draft.
shady i'd consider late in the second (i'm in a 10 team league). have concerns about our o-line and other bills poaching red-zone carries. i will probably avoid him, though.
