I see a lot in ZubyRick Pitino has been to 7 Final Fours. Name me the big guy on any one of those teams that was better than "fine". Marty Conlon? Nazr Muhammad? Gorgui Dieng?
In his system you don't need stud bigs. "Fine" is fine. Zed and an improved Zuby with Maker/Drissa giving you 10-12 minutes off the bench would be more than enough. Another solid big wouldn't hurt but to say without a stud we wont compete is a little over the top IMHO.
In fairness, I will say I'm higher on Zuby than most around here. I expect him to make major strides this year into next. That dude has stuff you can't teach: elite athleticism and non-stop motor. He runs the floor like a f***ing gazelle. You can teach guys like him to shoot. You can't teach them to want every damn rebound or to run the floor like Obi Toppin. They either have that or they don't and he has it.
