They fit Dallas' scheme better, Dallas also had a better roster strategy than Cavs' "surround Bron with shooters"
As individual players I agree on Tyson but 10/11 Marion being better than 08/09 Mo is debatable. Mo is broken now but he had a great season that year.
If Hughes didn't get hurt and have his brother get killed the cavs would have won a title with that team. Hughes loved basketball before his brother was murdered. He was lethal slasher and a gym rat before his brother died.
