"Gordon Hayward and Marcus Smart got tangled up in practice on Wednesday and Hayward proceeded to attempt to dunk everything the rest of practice.
Advice: Smart doesn't back down from anyone, even his own teammates. In this case, there was nothing wrong, just two teammates practicing hard, but it really sparked Hayward. His return hasn't been easy, but maybe his 30-point explosion on Saturday is a sign of the tide turning for the better."
Friction between these too was bound to happen eventually.
One guy is in the league because of effort and the other guy is here because he was anointed by the fans, front office, and coaching staff before ever even wearing a Celtics Jersey.
Hayward having a full year to recover from an injury returning to the court in "Fortnite Shape" definitely didn't help him build credibility or respect with his teammates. However, getting competitive in practice and going at people is a nice first step on the way back to NBA relevance.
