I will start with this. Clevland has nothing to worry about. Lebron will be better. He won't be 100% but he'll be fit enough to play. What they really need to worry about is if he can compete hard enough to overpower the stacked Celtics.
In the game where he got hurt he only scored 13 points. Although he does get around 6 or 7 assists a game Clevland dosen't need that from him. They need him for points. They need the NBA leading scorer Lebron not the couldn't properly shoot a free throw Lebron.
Good for Clevland:
. Lebron's perfectly okay and they end up destroying the Celtics
Bittersweet for Clevland
. Lebron's not okay but someone steps up and take his position as #1 scorer on his team
Horrible for Clevland
. Lebron has to sit out and it ruins the series for Clevland (not his fault if it does)
I'll leave all who's listening with this: If he scored 13 points with a bad arm against Chicago, how much (or little) will he score against Boston?
