There are plenty of people who are starting to believe that the improvement of Michigan football quarterback this offseason is real. But there have been others, in addition to head coach Kyle Whittingham, saying that Bryce Underwood has taken a big step forward. There are other players, too, such as Jordan Marshall, who said he thinks Underwood will be a Heisman candidate. He struggled in other games, too, like against Michigan State, where he struggled to complete passes in the second half. Bryce Underwood has a lot to prove for Michigan in Kyle Whittingham's first seasonIt's fair to be skeptical.
