Now that he has made the commitment to stay (at least this year), I could see him staying till he gets a head coaching job. That could be as soon as next year if we have the year we are hoping to.
Agree, though it could be TJ won't find the right HC opportunity for 2-3 years and stay in Ames too. Even if TJ does end up leaving next year Prohm will have gotten TJ local recruiting contacts and assuming it'll happen earlier than June CSP will have a larger pool of Assistant Coaches to better replace him. In the end TJ staying at this point is the best for him and ISU.
