Teams like Utah are paper tigers...one or two injuries (which is part of the game and happens to everyone) and their whole season falls apart.
A good team can manage through injuries because they have good depth. BYU is doing that.
That being said, Hans should know better...as others have noted, there's a list of high contribution guys that have missed significant time. If it was a national pundit I'd give them a pass, but Hans should know better.
The other thing is that our strength and conditioning program is VASTLY improved from what it use to be. Our dudes don't seem like they're built out of glass anymore.
