In his physical with the team, Hayes was found to have a heart abnormality in an echo stress test. He had undergone more testing, but it was announced that the team would void his contract.
Hayes was a guy the Kings could have used.
It's a shame that the thing that Hayes failed his physical for is the exact thing that made him a solid player.
For years in Houston, Hayes was the smallest center in the league, but got by against bigger competition due to being tough and gritty. He didn't put up the best statistical numbers, but Hayes is a guy who does all the little things that helps teams win.
A young team like the Kings definitely could have found value in a man like Hayes, especially at the defensive end of the floor where he played with heart and never quit.
For Hayes though, his heart will eventually be the thing that gets him back into the NBA.
