Fine assholes... since most of you are fathers, I'll let it slode and do my own research - Happy Father's Day!!
Garcia spent 5 years with the 9ers, had 2 winning seasons and won 1 playoff game('02), won another playoff game in 06 as an eagle, took two other teams to the playoffs (07 tampa and 01 SF)
Mcgahee spent 3 years with buffalo kicking ass but not making the playoffs, almost helping them to in his rookie campaign... between 08-10 the Ravens won 4 playoff games, albeit mostly with Mcgahee as the short yardage and TD back. 2011 he was an integral part of that dazzling tebow offense and they pulled that miracle win over steelers... 2012 he is oft injured and not the only back running in the manning system... they kick ass in the regular season and the ravens needed a miracle blown coverage at the worst time ever to win - although i certainly would not pin any of the Bronco success of 2012 on Mcgahee.
All in all, I guess they are pretty similar if you look at overall stats/fantasy points and consider their positions. I will say the "similar players" to Garcia are FAR more impressive, however (Marino, Unitas, Manning, Warner, Aikman, Thiesmann, Namath - vs Gerry Ellis, Marion Barber, Eric Metcalf, Jim Nance) . and I suppose the QB is more responsible for team performance than RB. I thought Mcgahee would end up looking way better but they are pretty even. Mcgahee's teams have more success but performance wise and importance to the team garcia looks damn good!!
Sweet parallel Escrow!!
