Can you correct grammar and tense?

There is a lot riding on their superstars shoulder's for the miracle to happen.

Why is he guarding Kobe Bryant when there are bigger guys that can guard him?

I don't know how he will play in the short term, but if you give him time, he will be healthy again.

He's played hard with/in every role he's gotten, whether the coach ask him to be a defender or more of a shooter, he's filled the role perfectly.

Our team will have a good idea of whether we are a good team or not over the next couple of weeks.

Nervous doesn't begin to talk about where my emotions lie.

The key to knowing when a player is getting back into shape is how high he can jump.

They need to foul before the 2 minute mark after which if they foul, the opposing team gets free throws.
