I think the Hawks are too deep at all positions and need to get rid of some of their talent for a star. I propose:
Speedy Claxton, Shelden Williams, and Josh Childress for Richard Jefferson
This gives the Hawks a SF who can play in the open court, has an outside stroke and can also excel in the half court game, as well as defend.
This trade also takes out the worry of having to sign Childress as well as gets us out of Claxton's terrible contract and open the PG jam of 4 to 3.
Further, gives space for Mario West (lock-down defender) and Solomon Jones to get into the game, as it sounds like they have been playing amazing in training camp.
Imagine:
PG: Ty Lue, Acie Law, Anthony Johnson
SG: Joe Johnson, Mario West
SF: Richard Jefferson, Marvin Williams
PF: Josh Smith, Al Horford, Solomon Jones
C: Zaza Pachulia, Lorenzen Wright
This trade does not hurt cap wise (essentially the same, except that Richard Jefferson locked in).
This second unit complements the first extremely well.
Lastly, at the end of the year, the Hawks then let Ty Lue, Lorenzen Wright, Anthony Johnson, and Salim Stoudamire walk and sign Gilbert Arenas (close friends with former college teammate Richard Jefferson)to a max deal (which will be about 14 mil). Finally, allow Josh Smith to get offer as restricted free agent and match it - signing him now does lock him up and potentially for cheaper, but then takes up our entire cap space preventing signing of Gilbert, as we can go over the cap to match him as a restricted free agent.
Yes, this will be expensive, but by this time the ownership group situation should be figured out and the Spirit will be looking to finally contend.
Imagine a starting five of Gilbert, Joe, Richard, Josh, and Zaza with off the bench of Acie, Marvin, and Al. OUCH!
