Toronto has a real good roster, a deep bench and a lot of talented players. During last summer the team management did an incredible job, we rarely could see a better job in only one summer. At the beginning of the regular season Toronto had the potential to do better than what has been done so fare…so much better! Turkoglu impressed everybody during the playoffs and Toronto literally “stole” him to Portland, Bosh put 25 lbs of muscles on and he was willing to become more and more dominant on the field, Bargnani and Calderon were happy and full of enthusiasm (and 50 million dollars each…ouch!).
The main goal of the new Raptors was obviously to improve the poor defensive side of their game, and coach Jay Triano apparently worked on it.
Everyone in Toronto was ready to become relevant in the Eastern Coast.

It’s almost two month into the season, and it’s seems this was all talk. Nothing more. So far, the team has played little or no defense, allowing opponents to score 108.7 points per game (146 to Atlanta – definitely a good team, but not the Lakers), which is the second worse record in the entire league .
The problem is simple and I tell you straight: Calderon's defensive inadequacy!
And this is enough for the moment.
Now let’s have a look at the attack team play: Turkoglu seems the ghost of the terrific player we saw against Cleveland in the Conference Finals, but this is comprehensible (new team, new coach, new teammates…new life) and it's just a matter of time. The real problem is Chris “I never pass the ball” Bosh; alright he scores 30 points, but to put up these big numbers he takes 30 shots…30 SHOTS! Come on, you can’t do that, boy!

So, what now? What could the Raptors do to improve on both sides, attack and difense?
• GM Brian Colangelo could try to trade Bosh or Bargnani to get a real defensive player in the paint. A dream lumberjack-style player could be Carlos Boozer. I would suggest to trade Bosh instead of Bargnani because CB4 will likely go away at the end of the season anyway. But Colangelo won’t do anything like that;
• Colangelo could try to trade Calderon too, or better, he should try to trade him. I repeat, it’s a real pain to see Calderon defend. This option is still improbable, but less improbable than the previous one;
• The third option could be firing Jay Triano for some defense-addicted coach. And that’s probably what is going to happen before the end of the season. There were rumors about the Italian coach Ettore Messina, 4 times Euroleague winner as a coach, now at Real Madrid, but at the end nothing happened.
I would hire Messina right now, I would definitely give him a shot.
