Tom Brady is the greatest football player that we have ever seen. His greatness could never be overstated. I don't even know where to begin with his accolades. Let's see 6 time Super Bowl Champ, 4 time Super Bowl MVP, 3 time league MVP, NFL Comeback Player of the Year, 14 time Pro Bowler, 2000's and 2010's NFL All-Decade Team, and one of the best NFL combine pictures of all time. On top of that, he has taken the Buccaneers to the NFC Championship game in his first season with them at minimum. This is a 2006 Tom Brady away jersey signed and inscribed "Let's Go!" with a LoA for game use by Mears and autograph by Tristar and Steiner. The signature is huge and very bold and the jersey has a grade of A5 by Mears. 
 
Mears grades ANY modern team issued jersey an A5 no matter what unless there is other provenance from a player, player personnel, equipment manager ect. I've seen plenty A5 grades get photo matched.
