Question on 2010/11 Contenders

[Clipnation]

So kind of new to collecting ( as in got back into after years), and Im trying to figure out a few things about this set.

There seem to be different versions of each rookie card in the set (as seen with different patch logos).

ALot of people are claiming this to be Short print, but I cant seem to find a list that matches. All i Can find is this:

QUOTE:
“Unlike football, where there were more than 100 rookies in the autographed Rookie Ticket insert, there are just 35 rookie players in Contenders Basketball,” said Panini Basketball Brand Manager David Porter. “But even with a considerably smaller rookie checklist, some of the Rookie Ticket cards were still produced in fewer quantities than others in the set.”

Each of the following players had cards short printed to 499 or fewer copies:

Hasheem Thabeet
James Harden
Tyreke Evans
Jordan Hill
Brandon Jennings
Tyler Hansbrough.
These players had cards in Playoff Contenders that were produced to 649 or fewer copies:

Blake Griffin
Dante Cunningham
Earl Clark
Jonny Flynn
Stephen Curry
Terrence Williams"
