From what I was able to track down, it looks like 25 out of 54 players saw action in 2012. The first 11 players taken saw significant playing time. Those guys were :
A. J. Soares
C. J. Sapong
After that it became kind of a crapshoot, with not a lot of correlation between position picked in 2011 and playing time from 2012. Here's what the graph looked like.
