Bargnani has come into every season bigger than the one before. Photos can only tell part of the story when it comes to something like this depending on what angle the picture was taken at or what have you. All i know from watching him and this team for the past 5 years is that yes he has undoubtedly put in good work in the gym pretty much every offseason.
The glaring problem with his game is not the effort off the court, it's the effort on the court.
And for what that first video shows, i still think Bargnani
is a good offensive player. That part of his game has not gotten worse. It's the defence and the defensive effort that's a disaster.
