Please help

Just played a guy twice tonight who had a mostly amy team and ruby lebron at point. He played decent but he never took lebron out the game he played he whole game and never once played like he was tired. He just attacked me all game and somehow is lebron was so much faster than my 98 lebron. Not to mention he got every bump steal known to man and Amy Jeff green was the best player on the planet. I could care less about equalizer and all that. He was a good player and didn’t run five out, but I’m just baffled how he didn’t sub him out not once and he never lost effectiveness. And to add insult to injury he actually had 4 players he never subbed out that logged 20min.
