Bottom line, there need to be significant changes to address this glaring issue with their ability to physically match up.
It has shown up as a problem throughout the playoffs. Luckily the Bulls lost their only NBA point guard and the Wizards had no bench.
You can't give up size, length, speed, athleticism, and offensive talent at so many spots in the starting lineup. You can't be at a deficit in so many of those areas against playoff caliber opponents. Your starting lineup has to present more of a challenge than that.
Heart, grit, and a dynamo point guard can only get you so far.
At least we are getting Fultz. That will help.
