Yep...and you could further limit that to financial dynamics. It's one thing to "break the bank" for football, totally another for baseball....and that's what it would have required to get Sully, Schlossnagle, Holliday or O'Connor. And on the last two, you would have had to pull him from his alma mater or pull him from the program he resurrected from the dead and built into a powerhouse, respectively.
Other than those four, all the other potential candidates were about the same. Personally, I liked Lemonis...and had Kingston second. Lovelady would have been similar to those two.
