Building Around Cooper: A Backward-Looking Thought Experiment

[Smitty]

I put this list together because we talk about adding guys via MLE or TPE and wanted to see who those guys actually were.

UFA's that could be potential gets with the MLE:

Guards              Wings                Bigs
McCollum          LeBron             Vucevic
Simons             T. Harris          M. Robinson
Sexton             Hachimura         Landale
C. White            K. Ellis              
Grimes             Middleton*                
Dosunmo          Kuminga (TO)             
Gillespie                                                                                   
Alvarado (PO) 


RFA's that could be potential gets:
J. Ivey
P. Watson
B. Mathurin
T. Eason


Trade options with the TPE or MLE:
Josh Hart $20.9M
Monk $20.2M
Curuso $19.5M 
Nembhard $19.5M 
Dort $18.2M (TO) 
G. Allen $18.1M
Strus $16.6M 
Schroder $14.8M
Lavert $14.8M
Moody $12.5M 
Isaiah Joe $11.3M
Nesmith $11.0M
McConnell $11.0M
A. Black $10.1M


I don't mean to imply that all of the UFA's will accept that little or that some of the lower tier will cost that much, just the list of names available. 
I don't mean to imply that the RFA's are available or realistic gets, just that they are restricted free agents. 
I don't mean to imply that the players listed in the TPE/MLE trade section means the other team will be willing to trade them to get off their money, or that the Mavs should go after them, just that they fit in the salary slot available to the Mavs.
Of course, there are a number of SnT/Trade options out there but didn't feel the need to get into all of that.

Knowing the names now, who and why should the Mavs prioritize this summer?
