With regard to Rhoda, he's basically got the passing skills of Mitch without the ability to run...oh, boy! In addition, he adds nothing to the future of the Gophers. At least with Croft or a freshman we are possibly developing someone who may play in the future.
As to the running game, the stupid hurry to the line, get in position, stand up and look at the sideline, get back into position and then pretend to option but actually run through the tackles may be the least imaginative and is absolutely the least effective offense a Gopher team has had in memory.
We have what we have, it's up to the HC and OC to make something, anything out of what they have. So far they have demonstrated that they cannot do so against B1G level opponents.
