I'm all in on Pitts at 3 now, think I've come to the realisation that he's just the most impactful player we can pick there, if we trade down with Carolina we may well mess out (probably would still take that chance if the offer matches what we should get though). Sewell is an absolute stud of an LT, but he's really not going to move the needle like Pitts can. Chase is an alpha WR but he's not as big, not as strong, not much faster if any, doesn't get the separation and of course nowhere close to the blocking skills of Pitts. Passing on him may come back to haunt any team that does.
The problem for me is college production. In last two seasons Pitts produced like an average receiver, not a top receiver.
