6. Matthew Slater
Matthew Slater has played the most games for New England of any player not named Tom Brady, having suited up for 239 games for the Patriots.
Drafted as a wide receiver in 2008, Slater would mold himself into quite possibly the greatest special teams ace in history. He is an eight-time All-Pro and 10-time Pro Bowler and was a member of the Patriots' last three title teams.
Slater was regarded as a consummate professional and was recognized for his admirable character with the Bart Starr Award in 2017 and the Art Rooney Award in 2021. He was also a 13-time team captain. For as exemplary as his on-field play was, Slater's character was considered even more exemplary within league circles.
Noticeably, no current Patriots were handed No. 18 a season after Slater retired.
Like many others on this list, Slater was named to New England's All-2010s and All-Dynasty teams. Special teams players historically haven't garnered a lot of attention for a bust in Canton, but if any player could break through, it would have to be Slater.
