I thought he would likely return, but this takes so much guessing and hand wringing off the table. I echo others in calling for his number to be retired at the final home game next season. Kalk should end up #2 all time at Creighton in my book (with respect to Silas and others).
Also agree with others that this completely alters the expectations/trajectory for next season. Jays should be a Tournament team. If they gel early enough, they could do some damage.
Go Jays!
