They got the best coach possible for their program.  Having lived through the 10 year war, let me say there is no better feeling than beating Michigan when they are really good.  But, it also means being prepared for the most horrid feeling possible, losing to them.  It will happen.  

But, the rivalry will be back to what it was in the late 1960's and 1970's.  Get ready for the joy and misery.
