Clearly without Jordan they are worse off, but just how much worse off. They still have cap space and they still have Dirk, Parsons, and Matthews. They also have Felton, Harris, Villanueva, and Dwight Powell under contract. They drafted Justin Anderson.
That back-court and wings aren't that bad and Dirk is a good start down low. They clearly need some big man help. Say they go after a guy like Josh Smith or Jordan Hill or Tyler Hansborough, and other players in that range. Let's just say they fill the roster with those types. Or maybe they go hard after Kanter and put OKC in a weird spot.
Where does that leave them in the West (assuming no Kanter)?
I'd say there are clearly 7 teams better than the Mavs - GS, LAC, OKC, SA, Mem, Hou, NO
After that though the team above is certainly in the mix for that final playoff spot with the likes of Phoenix, Denver, Utah, Minnesota, Portland, LA Lakers, and Sacramento.
In other words even without Jordan the Mavs still have a shot at making the playoffs. Even if they don't, it doesn't look like they will crater, which likely means Boston will be getting the pick from them. Let's also not forget there are going to be some bad teams in the East which should help boost Dallas even higher.
All and all I think Boston gets that Dallas pick, which will probably be around 10.
