I have to respectfully disagree with those who feel that without this year's version of Tevez, Juve would still be in first place.
If you factor in the largely ineffective performance of Vidal this season, Llorente disappearing off of the face of the earth, the continual decline of Pirlo, the season long absences of Barzagli and Asamoah, then I think that the presence of Tevez has been far more important this year than last.
With the role that he is playing this year, the extra freedom he is given, this has allowed Juve more possession, and taken the burden off of the team in ways that are evident on the pitch and in ways that are not tangible.
He has not only taken on the role of leading goal scorer, but he has also taken over the role of the engine of the squad this season, a role that was largely held by Vidal the previous 3 seasons.
Now, I don't think that Juve would have fallen apart this year, but first place? Probably not.
Regardless of whether or not Roma throws points away, the topic at hand is where this club would be without Carlitos
