There have just been so many misses at WR in the past and if you asked about Perriman before this season most people would not have had much confidence. The fact he has stayed healthy is really good and if he can continue his arrow is pointed up.
Guard and center seem pretty important if not most important on offense for me. We need to backfill for eventual Zuttah leaving and Jensen\Urschel are backups at best. Unless we resign Wagner I see Lewis as RT in the future.
WR wouldn't surprise me but I don't think early unless someone falls. TE is quite backlogged with Pitta, Williams, Waller, and Boyle. Something will have to give here.
