When Fultz committed to UW, he was under the impression that he was going to be playing with Chriss (many thought he would take a year to develop) and Murray. Honestly, a team with Fultz, Murray and Chriss would have been dangerous this year. But both played well enough to go in the 1st during 2016, so UW had literally nobody else on the team other than Fultz.
Either way, you can't question this kids character, and seems to have a lot of high quality individuals around him.
Even his coach doesn't feel their record has anything to do with Fultz.
“Our record and the absence of wins had nothing to do with him,” coach Lorenzo Romar said. “You can’t point to Markelle."
“We just didn’t – all of us – coaches and players didn’t get it done. As the season went on when conference started, we didn’t shoot the ball well. … There were probably 10 games that we had a chance to win and didn’t get it done. That just means that we weren’t good enough to get it done.”
