Bits and pieces of gray stubble jut out from of his chin and cheeks these days, hard to notice if you're not looking close enough.

A black brace is always secured to his surgically repaired left knee.

His hair is shorter, showcasing a slightly receding hairline.

One careful look at Tom Brady might reveal that he is celebrating his 35th birthday Friday.

Then the three-time Super Bowl champion quarterback of the New England Patriots takes the field at training camp, the unquestioned leader of the team appearing as driven and determined as ever despite entering his 13th season with the franchise.

''I still feel like a young kid out here trying to earn a spot and I think trying to be a good example,'' Brady said Saturday. ''Obviously, I have more experience than most of the guys out here, but you still try to bring enthusiasm and leadership and try to go out and do your job.''

After February's 21-17 loss to the New York Giants in the Super Bowl, Brady's record-tying fifth championship game appearance, the organization clearly made a concerted effort to try and make that job a little bit easier, bringing in a bunch of familiar faces from Brady's unparalleled past.

Offensive coordinator Josh McDaniels, who guided the Patriots' record-setting offense in 2007 when Brady tossed a league-record 50 touchdowns, is calling the plays again after serving as head coach of the Denver Broncos and offensive coordinator of the St. Louis Rams.

Receivers Jabar Gaffney and Donte' Stallworth, both members of that 2007 squad that went 16-0 in the regular season, also are back in the fold, adding two more weapons to Brady's dynamic cache, which already included receivers Wes Welker and Deion Branch, and tight ends Rob Gronkowski and Aaron Hernandez.
