I don’t feel OL is the biggest need. I feel that O-Line health is the biggest part of the shortcomings.
That and playing Jonah over Limmer
OL is a need if you consider they have to spend money or draft capital on LT whether it's paying Jackson or finding someone else.
I also want a big play WR to pair with Nacua considering Kupp may only have a year or two left at best and certainly both of their injury histories are an issue.
I like the Warren kid from PSU for TE. Right now he is considered a high 2nd rounder. So maybe that's a guy you can get with a trade down or trade up. I would prefer more picks, to fill those holes at CB, WR, TE, and maybe a QB prospect that can sit a few years.
