For what it's worth, I've seen many more articles saying that Glennon is the only QB "shining" at the senior bowl. Bleecher Report seems to be the only one saying his stock is falling.

At first, I didn't want to go near Glennon, at all. Then I watched a bunch of his games. Now, I would be very excited if we took him.
