I actually don't think he is. Butch has recruited a QB, an RB, and a bunch of WRs who are/could be great players but don't fit his system. It's played a huge part in his struggles at Tennessee. Jauan Jennings, Josh Malone, Marquez North, Marquez Callaway, Jalen Hurd, and Quinten Dormady are all examples of highly recruited guys who don't exactly fit what Butch is trying to do on offense. In order for his offense to succeed, he needs a mobile QB, a quick RB, and several quick slot receiver-type of WRs. While at Tennessee, Butch has played traditional drop-back QBs (Worley/Dormady), a big bruising RB (Hurd), and tall WRs that are deep vertical threats (Jennings, Malone, North, Callaway) for significant periods of time, but within the confines of his system.
Dobbs, Kamara, Tyler Byrd, etc. are examples of guys who did or do fit what he's trying to do, but he didn't develop them adequately or use them correctly. The way he used (actually, didn't use) Kamara during his time here is coaching malpractice.
Butch is an average at best (and downright poor in 2017) coach when it comes to evaluating and developing talent. He's above average, bordering on great when it comes to acquiring it.
