Things Rondo could do to avoid trade rumors in the future:
1. Work on his attitude;
2. Develop his jumper;
3. Learn to hit free throws;
4. Bring consistent effort at all times;
5. Don't disappear for the last quarter of the season.
That's perhaps harsh, but I also think it's fair. He's a great player, but he's not flawless. As long as there are big holes in his game, the team will inevitably explore upgrades.
"develop his jumper" - i thnk he has worked hard on this part of his game - but his shooting form is so fundamentally bad, it makes improvement very difficult.
"learn to hit free throws" - ditto, plus the added problem that i think he now has a mental block when he goes to the line.
"don't disappear for the last quarter of the season" - emotion plays a big part in Rondo's game, i thnk he's actually a little fragile in this area, though when he is in good shape emotionally and feels wanted, he will literally give the Celtics his right (or left) arm in an effort to help the team. also, while you may not want to hear this again, it's not any less true - Rondo was torn up over the Perk trade and it threw him off (then again, it threw the whole team off).
one other thing - i don't blame Rondo for being angry over the way Danny has shopped him.
