Ravens center Matt Birk filled in today on SI.com for a vacationing Peter King in King's "Monday Morning Quarterback" column slot.
In his "10 Things I Think I Think," Birk, a former Viking, predicts Brett Favre will play for Minnesota this year. The six-time Pro Bowler also makes the case for the players of today giving more back to NFL retirees.
And here's what he had to say about Steve McNair:
A quick word on Steve McNair: He was the definition of a gamer. His toughness and grit are legendary. Not only was he out on the field every Sunday, but he also played at a high level. That is what great players do. A lot of guys can play well when they feel good, but the season is a grind. A professional gets his body ready for every game, regardless of what injuries he needs to overcome.
