NFL assistant coaches are some of the best people to know for those looking to learn more about the game.
That has been my experience in covering the NFL since 1998.
I've helped push for better media access to assistants through the Professional Football Writers of America. I've also learned more about some of the issues important to coaches, including some outlined in this recent story about the NFL Coaches Association.
The chart shows NFLCA team reps as the association talks about forming a union.
Kevin Spencer (Cardinals), Johnnie Lynn (49ers), Dan Quinn (Seahawks) and Andy Sugarman (Rams) are the reps for NFC West coaching staffs. The 49ers' Jimmy Raye is president of the NFLCA executive committee.
It's not clear yet whether the NFLCA will move to unionize and such an effort would face a challenge even if the association did decide to move in that direction. But as coaches consider their options, these assistants presumably will be active behind the scenes.
