Iowa is much better equipped to have a significant injury to Bryce this year, rather than last. Overall depth and the ability to have multiple people fill in would not be the worst thing in the world. Marble will be much better this year, he will be stronger and better prepared to play PG if he has too, Hubbard is mature and should not rattle easy, given all he has been through, throw in Oglesby to help out and yes, it would be devastating, but it would have been worse last year.
