Tua had a good year 6-3. Jackson played almost the full season at a reasonable level. Iggy was a waste of a first round pick on a developmental prospect, not that this has anything to do with the point we are discussing but nice attempt at a deflection.
If we don't come out of FA and the draft with at the very least 2, probably 3 starting receivers (WR and TEs) then it will have been a colossal fail at giving our young QB the talent he needs. If we are relying on the motely crew you mention we will never get anywhere with this offense.
