Concerns are still concerns
Going into the season, there were concerns about offensive tackle and wide receiver. Four games in, those are still issues for Michigan football.
Donaven McCulley is a solid piece. The 6-foot-5 former quarterback is just going to face a lot of attention, and some others need to start making plays more consistently, such as Channing Goodwin, who has had issues with drops.
Getting Hogan Hansen healthy is paramount. He could be a difference-maker in the passing game. Marlin Klein is another.
Andrew Marsh has a ton of potential, but we'll see how much he's used as the season goes along after some freshman mistakes in the first few games. The talent is undeniable, though.
Evan Link has held up fine at left tackle. Andrew Babalola probably would have been better, at least as the season goes along, but Link is better than he was at right tackle
Andrew Sprague looks like a player. Greg Crippen played like an All-Big Ten center against Nebraska. If that continues, and more wideouts make plays for Underwood, Michigan could be dangerous.
In many ways, it already is.
