We don't really have a 4th TE, anyone better than Raymond on the team right now? we can replace Bars with a LS. Either Betts or Fitts are our choices right now and just liked Betts more. E Hall was rated higher than Ridley on some draft sites so the only way I could fit him in was to place Patterson in the running backs room which seemed ok as we carried 5 last year.
You can list 5, 6, 7 or 8 WR if you want. 7 isn't extremely uncommon.
Patterson will be listed as a WR, that's what he is, and is a lock.
He could be listed as a KR, but I have no doubt Nagy paid that $$$ for him on Off. Plus it wouldn't shock me to see Whyte win KR.
Bears could go 3 TE and see Nall as their 4th... where he could be PS, or RB. I'd be surprised but I'd understand if they actually outright 'convert' Nall to TE.
