As a die-hard lifelong fan it's really hard to say this but I really see PSU winning four NTs in a row. They are just a machine and very young. I think they drop off after that (a la 3 time winning MN in the early 2000s) but right now they are the best around.
Hawks will get back to form and continue to dominate the wrestling world but this current batch is the perfect storm for Cael. Hopefully this won't lead to a bunch of freakish good wrestling recruits for him, though. I doubt it because guys that talented come along rarely - i'm feeling like OSU has the next up and coming batch and hopefully next year's class has some in it for us.
