I think we stick with the guys we have in the room already (plus Noland here soon) if Day/Dennis actually let an open competition happen. We have a a really good QB in the program already...that may be McCord if he improves in the offseason and ditto for Brown...Kienholz has all the attributes I want in a QB and brings more mobility. Noland is only a frosh next year, but that southpaw can sling it and is also above-average athletically. Assuming there are no transfers, bringing a 5th QB in doesn't make sense to me with how we have recruited QBs and what is out there in the portal currently.
I have seen Finn from Toledo mentioned and I think pretty highly of the kid, he is an exciting player. But looking at the stat sheet, here is Finn: 65.1% completion rate, 2,384 yards passing, 21 TDs to 8 INTs, and a 69.7 QBR...that ain't great playing in the MAC. Let's compare to McCord: 65.8% completion rate, 3,170 yards passing, 24 TDs to 6 INTs, and and 84.1 QBR. You could argue that Finn would be better with better talent around him. I would take him if he wants in to compete for the job, but he might not be an improvement is all I am saying.
As to the Williams, Maye, etc. conversation, they are all going pro and that leaves very little in the portal at QB (to your point). Arch Manning can come to OSU on the one condition that he gets no NIL. We don't need Ewers 2.0 here again with a good QB room. Even then I am hesitant, I think the headache isn't worth the potential upside. As we currently sit, Finn would be the only one worth looking at.
