Cooter served as a graduate assistant for Tennessee in 2007 and 2008. He was then hired as an offensive assistant by the Indianapolis Colts, working for them from 2009 through 2011. Cooter served as the offensive quality control coach for the Kansas City Chiefs in 2012 and then joined the Denver Broncos as an offensive assistant in 2013 with the support of Peyton Manning.[5]
Detroit Lions
The Lions hired Cooter as their quarterbacks coach in 2014.[5] After the season, they denied a request of the Chicago Bears, who wanted to interview him for their offensive coordinator position.[6]
The Lions promoted Cooter to offensive coordinator during the 2015 season, after former offensive coordinator Joe Lombardi was fired midseason.[3] He remained the offensive coordinator for the Lions until January 1, 2019, when it was announced that the Lions would not be renewing his contract.[7]
New York Jets
On February 8, 2019, the New York Jets hired Cooter as the running backs coach under new head coach Adam Gase.[8]
Philadelphia Eagles
While not officially on the coaching staff, Cooter spent the 2021 season as an independent consultant for the Philadelphia Eagles.[9] Head coach Nick Sirianni, who had coached with Cooter with the Kansas City Chiefs 2012,[9] "nonchalantly" announced this during a press conference after tying the New York Jets early in the season, stating:[9]
I thought the operation was really good. I was calling the play to [offensive coordinator] Shane [Steichen], Shane did a good job of getting the call in there when we're in 2-minute situations. [Passing game coordinator] Kevin Patullo is really doing a lot of, "Hey, here's our scenario of what we're in." And Jim Bob Cooter is getting all the scenarios from the 2-minute around the league so we can prepare for it.
During follow-up questions, Sirianni went on to clarify Cooter's role with the team:[9]
Obviously, he's got a lot of experience and he's a great football mind. I think very highly of him. So, he's doing special projects for me and consulting here, which has been great. If I see a play or if we talk about a play that -- I just think this is really important. When you put a new play into your system that you maybe saw on tape, I think it's very easy for a coach to do that and be like, "Oh, I saw that on tape. This looks great. I'm just going to through it my offense." Well, do you know everything there is to know about that play? I'm not saying Jim Bob knows everything there is to know about every play, but what he is able to do is while we're doing something else, he's able to go research that play. I've already seen the benefit of that with a couple new wrinkles we have in this offense. So really excited to have him. I haven't really ever had that on a staff, and sometimes it deters you from putting in a play that you might like. So we have really gotten a lot out of him and really excited he's here.
Cooter is from Fayetteville.[12] He was arrested for driving under the influence in June 2006, and was suspended from the Volunteers as a result.[5] In 2009, he was charged with aggravated burglary after climbing into a window and getting into a woman's bed.[12] The charges were later dropped.[13]
