The terms “All-Pro” and “Pro Bowler” get used interchangeably, but they’re much different.
To be named to the Associated Press All-Pro team means you’re the absolute best at your position that season. One player for each spot.
Being a unanimous selection means you’ve had an absolutely dominant season, and only two players got that honor this season: New Orleans Saints receiver Michael Thomas and New England Patriots cornerback Stephon Gilmore. It seems to be a precursor for Gilmore to win NFL defensive player of the year. The same voters who choose the All-Pro team also pick major awards like DPOY and MVP.
