Well, he is at least according to ESPN's Todd McShay, who in Monday's Insider article that ranked the top freshmen and sophomores in college football also listed a few other players whose draft stock moved in the past week or two.
Nassib was listed just under "stock rising" as one of the "almost famous" guys.
Here's the paragraph on Nassib:
McShay: Ryan Nassib, QB, Syracuse
We've typically saved this space for some more obscure, off-the-radar prospects, but this felt like a good week to feature Nassib. He's in the Day 2 range, like Glennon. He's still developing as a passer (he throws too many fastballs) but he has a strong arm and has made some impressive throws under duress this season. He has passed for 579 yards, six TDs and zero INTs in his past two outings (wins over Connecticut and South Florida). The pre-draft process will be key for him, but I think he'll excel when he goes through it. He's really smart and a great student, from what I've heard.
