Let's see:
2012 Philadelphia Phillies
50% injuries (R. Howard missing the entire 1st half of the season, C. Utley missed 75 games, Doc was out two months)
25% Charlie Mack
25% Ruben Amaro (He panicked, and broke the team up, instead of just riding it out.)
2012 Philadelphia Eagles
40% Andy Reid and his staff
30% The defensive unit as a WHOLE (players)
20% Michael Vick (he shouldn't get the front of the blame, but he wasn't innocent in this shit, either)
10% that offensive line
2012 Philadelphia 76ers (who are free falling right now)
40% Andrew Bynum (yes, because the team has been in limbo waiting for him to show up)
30% Doug Collins
25% the soft-ass frontcourt
5% Evan Turner
