With or without him the Lakers has no chance against any team their are playing against in next 5 games because we are talking about Oklahoma, Warriors, Clippers, Utah and Portland. All of them are playoff teams and all are fighting for a better spot so Lakers should be an easy target for them.
Lakers already out of the playoff picture, they don't have a chance of course, and even if they win.
There is no assurance that good teams are always winning, did you see the Mevericks routing the Warriors at their own home court? That explains.
Right now that playoffs is coming, team are more critical on getting wins especially those teams with a chance to get into the berth. Win is a must for them and teams like warriors who is already on top for the playoffs will play not their a-games to avoid injuries.
