LSU built theirs about 5 years ago so it is pretty big and still new. I believe Michigan also has a recently new built training facility. Auburn is in the process of building out a new one. Clemson probably has the nicest right now since it is just completed. I have seen digital renditions of it and it is sweet.A factor against UCLA is that its gym is pretty small and unimpressive compared to some other schools.
Which schools have the biggest and/or best facilities? I hear Utah and LSU have nice gyms.
