Even if Willis is all that, he's a Work In Progress and will take years to develop -- if and only if he has the maturity to be coachable, if he is given the RIGHT coaching and has an O-line that can protect him, as well as having weapons at his disposal.
Not all WIPs turn into Josh Allen. Plenty of them are more like Ryan Leaf, Johnny Manzell, JaMarcus Russell and David Carr. I don't know about Willis's maturity, I don't know that we have an offensive coach capable of molding him and we certainly don't have much of an O-line right now. Our weapons at WR are very good until you get past Lockett and DK, and our two RBs are very good until Game 5 when they're both on IR.
Best to get the other pieces in place before rolling the dice on a risky QB that did not play against elite competition in college. The 2023 draft has a much better QB selection, and I'm afraid we'll need to look at 2022 as a bridge year.
