As an impartial FF coach, I would call BS on some of that.
1) Bradford will start for a FF team. No one is going to have him on the bench with his projected numbers.
2) TA may not be better than a 3 as a receiver based on his first season but that's only if you don't also score on run plays/yardage and ST. This is the subtlety of FF that you don't get from numbers. He's explosive, he's not a rookie anymore, Sam is back, Rams have a run game, the blocking will help him too on run plays. Although, with Bailey out, if no other WR appears to be breaking out, TAs value go down. He's not a one man show.
3) Britt would absolutely be a late sleeper steal IF he looks good in TC and plays well in PS. If you aren't taking a flyer on a potential number one producer, who will you? He's done it in the past under Fisher, he loves where he is, the job is his to take with little competition, and Bradford is excellent going vertical when the opportunity is there.
4) If you grab Zac, you grab Tre late. Zac gets hurt, Tre could become instant money.
5) With the lack of play making TEs in the league, Cook could be quite the value. He was 11th in the league last season.
