Some of you guys ranking on Val or Vucevic must think Tyler Zeller is the worst center in the history of the league or something.
It might be nice if this team could get more rebounds than the other more than once or twice a year
Zeller, Vucevic and Val would all be decent big men a decade ago or in the 80's or 90's. The game is different now and that is what the hangup for a lot of people is. Certain things have changed especially in the last 2-3 years that have made them all a net negative to have on the floor.
1. Guards are having a terrible time getting over picks because everyone has learned some of Harden's tricks. Trying to go over a pick only to have I.T. or Harden or whoever pull up for 3 right next to the pick setter forcing you to run into them or they catch your arm in there is ending in very bad results. This is forcing big men to come out higher and accept switches and/or hedge really high because it is a far better to do so than not. Slow bigs are getting destroyed because guards are having trouble getting over screens successfully. Going under just leaves the ball handler open.
2. The screening action is all taking place above the 3 point line with shooters that are good enough to destroy you if not defended aggressively. Hanging back in the paint with your big men and just giving up jumpers isn't an option anymore because of the extensive use of the 3 point line and a resulting much higher efficiency. You CANNOT leave I.T. or anyone else alone to defend a ball handler and a screener, opposing teams will free up shooter after shooter and destroy you.
Because of those 2 things and probably a few others it is now impossible to both defend well with your big men and also rebound with them, pick your poison especially against the very good teams. If you have 2 bigs on the floor 1 is usually guarding a spot up shooter and the other is in the pick n roll at the 3 point line and quite often defending the shooter either out there or on penetration. It takes them out of the rebounding picture a LOT. You will not see the C's investing in anything resembling a slow big man who cannot defend out to the 3 point line and also not get roasted by penetration.
Rebounding must be a team effort now more than ever!!!
