is shaq the missing piece to lebron's championship puzzle?  

It might be, and it might be not. Shaquille is big and strong inside but is now in his late thirty's. It means that he lost some steps and some moves. He may have the hulking presence but lacking in some mobility. If Lebron is to win a Championship, it would require a team effort, and not on a particular player alone. The addition of Shaq had boosted Lebron's chances but is not a guarantee of a championship ring for him. Let's see in the coming season!

Oh,Shaq is old,and the team line-up of cleveland is still not top right now.

Shaq-King is the right tandem of the giant. they are most likely one of the best ever Duo in NBA. Best in the East vs Magic & Celtics. Shaq can possibly get is fifth before he retire.

I still don't know if they can do it. The big guy will help, but what they really need is an additional guard that can score besides LJ. Too much pressure was put on him to score from the outside. And like was said, shaq is gettin old and teams are better adapted to guard him now then they were in his prime. I still think they need a scoring guard before james will stop feeling like he has to do everything and they will have a shot at a ring.

shaq is not the missing but he's certainly a big boost to the cavaliers. I think they need a stretch power forward and as of now, they have also signed anthony parker and they might also get jamario moon. And i think the cavaliers have a great chance of winning the crown.

I don't think Shaq is the right person. He did improve his free throw percentage, so they can't Hack a Shaq at the end of the game any more.
