Ah, he'll be drafted, but Hoyer caused MSU fans fits. He often chokes in the big games. Anyone remember two years ago against BC in the Champs Bowl when he threw four interceptions and dropped the ball for a fumble?
At times he can be great, like two years ago against Purdue and Penn St., which he personally won for the team. He is a great kid, has good work ethics, and has had multiple coaches to work with. (The current coach, Mark Dantonio, is very good, a Nick Saban protege who was also the defensive coordinator for the Buckeyes when they beat Miami for the national championship in early 2000s.) His receivers weren't as bad as people say, though there were a lot of dropped balls.
Here's a Q&A he conducted with the Browns:

The O Line wasn't weak, either, except like the Patriots the Spartans have an undersized center who gets overpowered at times and a shaky RT who can get beaten on pass blocking because he's slow on his feet.
Any comparison to Drew Brees is crazy. Hoyer has shown he's a winner, but he'll make mental mistakes when the pressure's on. He's played great some games, then made too many mistakes in others. But his arm strength is definitely good, surprisingly so as he can make long passes on a rope required for the NFL, as is his mobility.
He's learned not to try to do too much. So a late round possibility for long-term grooming seems worth it.
