First point is spot on. I honestly would expect an announcement in the next 2 months, if he's gonna come to N it benefits him to commit soon to better our odds at other top flight players who would take a look at us with a qb like that.
On the callahan part, hard to say it never panned out- that class included a starting qb for a few years in zac taylor, a pretty filthy rb in marlon lucky, quite a few multi year starters and legit guys along the ol and dl, and this dude named suh who ended up being an all time unstoppable force and arguably the best defensive player in cfb history.... no a bad haul.....
