Teams from across the country are responding to Houston coach Kelvin Sampson's request for help for the residents of flood-ravaged Texas.

The Cougars' coach posted this message on Twitter on Monday afternoon: 

The response on social media has been overwhelming. The Bishop Gorman High School basketball team in Las Vegas appeared to send one of the first responses on Twitter. 

 

From there, Sampson kept retweeting messages of support.

 

 

It wasn't just basketball teams responding either. 

 

 

 

The Houston area has been beseiged by catastrophic flooding from Hurricane Harvey.
