Looking at next year, my assessment of where we're at:
QB--obviously set, I think everyone agrees with this. Mariota is a good back up, but if he leaves for a starting opportunity, we'll have options. Trey Lance is available; I loved his athleticism coming out of the draft. He's be fun in Kliff's system. I think it would maximize his talents too.
RB--I'd bring all three back: Bill, C-Rod (RFA I think), McNichols. With even moderate health at receiver, we've been able to run; Bill and C-Rod are a good match, and McNichols is a poor mans Ekler. I wouldn't be opposed to an upgrade though--just don't think the major resources for Breece Hall or Jeremiyah Love are necessary. I wouldn't gripe about picking Love in the 1st either.
WR--Hard to evaluate with all the injuries, honestly. We definitely need to add here. Alec Pierce is my #1 free agent, bar none. He's averaged 22.3 and 21.1 YPC the last two years respectively--with Anthony Richardson and Daniel Jones throwing. Imagine him with JD5. Someone like that can really open up the run game too. Bring back Deebo on a reasonable contract; Burks, LMC, and Lane round out our core. Much younger, faster, and healthier. Not opposed to drafting here either--Tate in that group would feed the starving kids in Indiana.
TE--I'm on the Pitts bus. I'm ready to be hurt by his tantalizing athleticism and underwhelming overall production, but I am onboard. I think he would do well here, with a legitimate OC and QB.
OL--least of my worries. Conerly is improving, Tunsil is an automatic resign, Cosmi a year removed from major knee injury, Biadasz, and Paul-Coleman battling for the last guard spot. Need younger depth though--I have not looked much at this group since it's good, as is.
