With WR $ getting dangerously close to QB $ it's going to be beneficial to take a WR almost every yr just for cap reasons. We really don't know what we have in Miller he has shown flashes when healthy which he has not been much. Upgrading the RB position would be easier on day 2 than getting someone better than Olave and Shaheed on day 2.
I would go with Tet over Jeanty due to the fact that Jeanty would split snaps with AK and maybe Miller. Tet would play almost every snap and be the big contested pass catcher we have been missing since Thomas got hurt and was never the same. Plus if Tet becomes what I think he will we have him for 5 yrs on a rookie deal before he commands big $
