Mike Glennon played and was never that good looked like a big stiff to be honest was like 5-13 as a starter, they drafted a guy to replace him number 1 overall and he parked his ass on the bench where he belongs and all of a sudden he's a $15m a year QB wtf.
He's literally got better by not playing apparently, NFL teams are really stupid.
I would rather take a flyer on a QB in the draft and bust out that way than pay Mike Glennon who's upside is mediocre at best.
Mike Glennon is never going to be a franchise guy or even a top 10 guy.
