Well, Kevin Wright took a serious look at Tech supposedly once upon a time. I believe that's when Dr. White was going to make Tech the only football program in IPS if I remember correctly. I think Coach Moore would win any where he goes. It might take him a while. The kids would gravitate to him. Perry hasn't always been a doormat. While that program has struggled in recent history, Craig Barr had some good years, and the program had some very solid seasons in the 1970's and 80's under Steve Purichia and others.
We're kind of seeing what happens when a great coach goes in there on the basketball side. Mark James took BD's boys basketball program and turned them from bad to mediocre into state champs in six years. Perry is moving in a positive direction right now with him down there.
To answer your question, I think they would struggle early, but I think they also know how to build programs...especially in Moore's case.
