So I found this article that I remember reading last year. It basically has the Madden development team talking about who their all-time "Dream Team" for Madden was.
It's probably not all 100%, but I have a feeling the All-25 team is basically going to be the entire roster in the article. Here are the names they mentioned...
QB: Michael Vick, Peyton Manning
RB: Marshall Faulk, Reggie Bush, Barry Sanders
FB: Mike Alstott, Marcel Reece
TE: Antonio Gates, Jimmy Graham, Rob Gronkowski
WR: Randy Moss, Brian Finneran, Jerry Rice
OL: Steve Hutchinson, Walter Jones, Orlando Pace, Jonathan Ogden
DL: Bruce Smith, Dwight Freeney, Warren Sapp, Jameson Konz
LB: Ray Lewis, Patrick Willis, Frankie Nax
CB: Deion Sanders, Champ Bailey, Dominique Rodgers-Cromartie
S: Ed Reed, Brian Dawkins, Sean Taylor
K: Adam Vinatieri, Mason Crosby
P: Shane Lechler
KR: Devin Hester, Dante Hall
Update: So far all the players in bold have been named to the All-25 team.
