Everyone knows the NFL draft is a collaborative process. Scouts, player personnel executives, general managers and even team owners have a say in the war room.

But who makes the final call for all 32 NFL teams? ESPN's NFL Nation reporters offered insight into just that Sunday. The reporters described the war rooms of their respective teams, giving fans a look into what they'd see if they were a fly on the wall at the end of April.

Here's a list of every team's final decision-maker(s):

NFL Draft Decision-Makers Team Decision-Maker Other Notables Buffalo Bills GM Doug Whaley Owners Terry and Kim Pegula, President Russ Brandon, Coach Rex Ryan, Pro Personnel Director Jim Monos, College Scouting Director Kelvin Fisher Miami Dolphins Head Coach Adam Gase President Mike Tannenbaum, General Manager Chris Grier New England Patriots Head Coach Bill Belichick Director of Player Personnel Nick Caserio, Director of Football research Ernie Adams, Michael Lombardi, Director of College Scouting Monti Ossenfort New York Jets GM Mike Maccagnan Front Office Assistants Rex Hogan, Brian Heimerdinger Baltimore Ravens GM Ozzie Newsome Assistant GM Eric DeCosta Cincinnati Bengals President Mike Brown Coach Marvin Lewis, Director of Player Personnel Duke Tobin Cleveland Browns VP of Football Operations Sashi Brown Pittsburgh Steelers GM Kevin Colbert Head Coach Mike Tomlin Houston Texans GM Rick Smith Owner Bob McNair, Head Coach Bill O'Brien Indianapolis Colts Owner Jim Irsay GM Ryan Grigson Jacksonville Jaguars GM Dave Caldwell Coach Gus Bradley Tennessee Titans GM Jon Robinson Denver Broncos GM John Elway Mike Sullivan, Matt Russell and Tom Heckert Kansas City Chiefs GM John Dorsey Oakland Raiders GM Reggie McKenzie Head Coach Jack Del Rio San Diego Chargers President of Football Operations John Spanos GM Tom Telesco Dallas Cowboys Owner Jerry Jones New York Giants GM Jerry Reese Philadelphia Eagles VP of Football Operations Howie Roseman Washington GM Scot McCloughan Chicago Bears GM Ryan Pace Head Coach John Fox, Director of Pro Scouting Champ Kelly, Director of Player Personnel Josh Lucas and Director of College Scouting Joe Douglas Detroit Lions GM Bob Quinn President Ron Wood Green Bay Packers GM Ted Thompson Head Coach Mike McCarthy Minnesota Vikings GM Rick Spielman VP of Football Operations Rob Brzezinski, Assistant GM George Paton Atlanta Falcons Head Coach Dan Quinn GM Thomas Dimitroff Carolina Panthers GM Dave Gettleman Head Coach Ron Rivera New Orleans Saints GM Mickey Loomis Head Coach Sean Payton, College Scouting Director Jeff Ireland Tampa Bay Buccaneers GM Jason Licht Arizona Cardinals GM Steve Keim Head Coach Bruce Arians Los Angeles Rams Head Coach Jeff Fisher GM Les Snead San Francisco 49ers GM Trent Baalke Seattle Seahawks Head Coach Pete Carroll GM John Schneider ESPN.com

For the most part, this is a list of wholly expected names. General managers comprise an overwhelming majority of the final say. Of course, this is largely the definition of what a GM is supposed to do; it's pretty reasonable to expect them to take the reins.

The more interesting teams are ones that veer away from the expected path. Only four head coaches appear to have the final say. One of them is New England Patriots head coach Bill Belichick, who remains the truest possible outlier in all aspects. Seattle Seahawks coach Pete Carroll has proven himself more than capable while working closely with general manager John Schneider.

The other two names, Los Angeles Rams coach Jeff Fisher and Miami Dolphins coach Adam Gase, are a little more concerning. Fisher has spent more than two decades on an NFL sideline and has gone over .500 six times. With the Rams recently mortgaging their next two drafts to move up to No. 1 in 2016, it might make more sense that it was a "head coach" decision. Gase, meanwhile, has no experience as an NFL head coach.

Ownership takeovers are happening right where most would expect. Dallas Cowboys owner Jerry Jones and Indianapolis Colts owner Jim Irsay are widely known as being among the most actively involved owners in football, and Cincinnati Bengals President Mike Brown was described as a "draft junkie" by ESPN.com's Coley Harvey. All three men have had varying levels of involvement over the years, most likely in accordance with their trust level of the front office.

Overall, though, this is more of an interesting look at a front office hierarchy than anything. Every front office is a collaborative effort. There's no one person smart enough or powerful enough to pull it off all on his own. So for all of the big names compiled in that list, most of the day-to-day grind is being handled by hundreds of names you've never heard before and may never hear.
