Not really. I mean, it wouldn't be devastating, but after the Hayward signing, we were talking about how we were the new Warriors of the East. To go from title contenders to lower seeded playoff team would be a pretty big gut punch. No Kyrie, no AD, hobbled Hayward. We would really need to bank on Tatum and Brown reaching perennial All-Star level soon.
I can't imagine this is the path Danny was hoping to go down. I imagine he is going to do everything in his power to make this thing work. Horford and Hayward are still on the roster - no reason to throw in the towel yet.
