Just a few of the non-QB or non-K/P that come to mind active on NFL teams. 
  
  
It's like everything in life - you get what you put in....and the Bills have not been as active in using Europe League as a developmental tool in the same way as say the Chiefs, Broncos and Pats. 
  
  
I guess the other way to also look at NFLEL is that you find out who CAN'T make it thus saving some $$$$$. 
  
Though the standard isn't always great, think it's unfair to think of it as only a QB and kicker league.
