Wilhelm and Wilcher, despite their limitations, are guys you know can contribute in the Big Ten. It can't be a teardown every single offseason if Fred is going to build anything. Of course both have been up and down but that was the story of Keisei last year and people were ready to run him out.of town on a rail.
Now I don't think it's the end of the world if you'd lose them, but I don't think you should be looking to chase them off, imo.
