Mo money (self explanatory), less problems (SEC style eligibility/compliance standards)
Tang doesn't owe us anything for hiring him from Baylor. He had offers before, he was just waiting for a good one.
That said, save for the Tomlin stuff Tang has everyone going for him at ol' KSU. Instant success, strong fanbase, consistently best basketball conference. The wildcard is how he feels about his bosses at each school, which can count for a lot (and was obviously the reason Frank bounced).
