I'm not just surprised that Antonio Gates didn't get in, I'm utterly shocked! He's got the most touchdown receptions of any Tight End in NFL history, 5 ahead of Hall of Famer Tony Gonzalez in 1 fewer season and he's #7 All Time in that category, the 6 above him (Jerry Rice, Randy Moss, Terrell Owens, Cris Carter, Marvin Harrison & Larry Fitzgerald, all Hall of Famers with the exception of Fitzgerald who will be eligible next year) were all Wide Receivers!
Whoever didn't vote for Antonio should lose their privileges, the only advantage that I can think of that Gates had over Gonzalez is that Antonio had back-to back future Hall of Fame quarterbacks throwing to him in Drew Brees & Philip Rivers, where as the only potential HOF QB that Tony had was Matt Ryan at the end of his career, and there's no guarantee that Matt gets in.
