Bruce Arians didn't get a head coaching job until he was 60 and he's since emerged as one of the NFL's best.

Arians wants the Arizona Cardinals not just to win games but teach football to his players.

“We have one of the largest staffs in the league, because I want small classrooms," said Arians. "Michael Bidwill was very gracious. Let’s say I have $450,000 to hire one coach. Could I have three for $150,000? So I have smaller classrooms, and more eyes. I had a different idea how I wanted to get rookies ready. We have two tight end coaches. We have three offensive line coaches. When we come to the spring, and we have 90 guys on our roster, we have two practices going on. I want to have enough quality people to go to that other field, and those rookies get those 48 snaps that day, and the veterans get 48 snaps, rather than the veterans getting all the snaps and the rookies get three. You’re not gonna find a diamond in the rough standing on the sideline. With the larger coaching staff, not only do we get the reps, we got ‘em coached. We’re bringing quality young coaches into the NFL. Our job is to make the game better, not just win games.”
