Kyle has built a decent program and its improving. His biggest warts are QB and the offense in general, but he reloads the defense every year and that is proving to be the most important, IMO.
Your hope of their demise for 15-20 years is wishful thinking. They are a middle of the PAC team and will get their occasional shot. Especially with an almost always underachieving UCLA, ASU in their division, UA who is inconsistent, and a pathetic CU without an identity. USC is the only real threat and they are equally struggling. It's as much or more about coaching and chemistry than it is about individual talent.
This is true time and time again at the college level.
