Think Philadelphia 76ers.
They were stuck being just OK. Sliding into the playoffs some years as a back end playoff team and then getting smoked in the postseason. So they decided to blow the whole thing up. Now granted, they went extreme and purposely put the shittiest team one could think of on the floor to get high picks.
It's not the model I think Dallas should follow. It's the thinking. Realize that this team is a back end of the playoffs, at best, team. It is not beating Philly or San Fran come postseason. So why keep being just "good", at best, with what we are putting on the field? Blow it up, at least offensively, and start over.
