Maybe, maybe not. Considering you have really not seen Sledge play at all, you are mearly speculating. You can't forget that Bubu played a decent amount of minutes last year so to say a year in the system doesn't give you a substantial advantage is stupid. If that were the case, why didn't Richardson start before Barnett at QB? Does that mean Barnett's ceiling is higher than Sam's or would you just be guessing? Give him time, if he busts, he busts. Or, like Diante Garrett, he might come out the next year and look like a completely different player than he did in the past. Just saying.
To sum it up. You don't know sh** about Sledge except that he doesn't play and Bubu plays in front of him. So with that logic, Percy wont ever play in front of Booker or Ejim down the road right....oh wait...that already changed.
Much of what you posted here is incriminating to your point.
1.) Sledge not playing as a freshman while Bubu got decent minutes as a freshman, if anything supports my contention that Bubu as a freshman was ahead of Sledge as a freshman. It is more speculative to suggest otherwise.
2.) Your attempt to support your stance with a comparison to Barnett and Richardson is frivolous except for indicating your lack of understanding the context of the discussion. No one is suggesting having a year in the system is not advantageous. Again, in the context of Bubu playing in front of Sledge, the players upside is what they can reach by 2013-2014. Although not fair, it does not matter if Bubu's play is better (and thus upside) due to being a year ahead in the system.
For your benefit, I will use a similar trivial football comparison. Would you start a freshman QB that had the potential to be better as a senior than your junior QB, even though that junior is currently better (perhaps due to experience) and will still be better the following season?
3.) Comparing Sledge to DG as a freshman is more speculative than anything I have posted. Sledge and Percy have little in common. Percy showed from the very beginning he had Big 12 talent and was our best center. It would take an idiot to think a 6-9 240 freshman with good touch around the basket would not eventually see some time iover a 6-5 "post". Sledge on the other hand got moved to shooting guard in high school, but is 5-7 and not currently a good shooter.
