Also, Shumate should be held with pretty decent expectations. He beat Rutger's Poznanski (former 4th place AA) via a 7-6 Decision at the same tournament that Poznanski beat Michigan's Rogers via a 5-2 Decision.
Unless he struggles tremendously or Hoffman soundly beats Geog and stays healthy and forces Geog down, I don't see anyone else starting for them at 184lbs this season. Sans injuries, mind you.
Also, I wouldn't be surprised to see Welsh get some spot starts in duals, if Shumate needs a break.
