Here's a Biggie: Purdue is injury proof this year. I'm not just saying that because they're practicing yoga which all but eliminates tissue injuries and pulls. Purdue can sustain any injury and still realistically make it to the Final Four.
If Kyle Wiltjer goes down for Gonzaga this year, they're done. He's just too huge a chunk of their offense. Same thing for Kaminsky and Wisconsin last year. The Badgers couldn't even beat Rutgers without Frank.
Purdue doesn't have that one guy that is so much better than his replacement. If Hammons goes down, Purdue loses a little on both sides. But Haas can do a reasonable job replacing his minutes, and there's still quality depth there with Jacquil & Biggie backing him up. If Purdue loses Raph, they lose a little on D, but they might actually improve on O. Though, I doubt it with as hard as Raph is working to improve himself this offseason. Plus, Raph's biggest contribution is leadership. He can provide that from the sidelines.
Purdue is stacked with ball handlers. They're stacked with shooters. They're stacked with bigs. Choo choo. All aboard. Next stop Houston.
