Expected. You don't pull the plug on a guy 14 wins into 2 years as a HC.
Single digit wins in two years - you make the call
1-3 win season - you likely make the call.
Middle of the road coach and season...back to back years - You wait.
Payton produced back to back mediocre seasons twice and a threefer once, 07-08 and 2014-2016. and Loomis repaid him with patience.
