CP3 was never really a true threat to leave, he just had a ton of leverage. Howard OTOH is a different story. As far as free agents and the Free Agency market it's never about 1 or 2 guys....
There are still players like...
Josh Smith
Andre Iguodala
Andrew Bynum
Al Jefferson
Paul Milsap
Brandon Jennings
Kevin Martin
David West
Lamar Odom
Monta Ellis
O.J. Mayo
Jarret Jack
Chauncey Billups
J.J. Hickson
J.J. Redick
Kyle Korver
Andrey Blantche
Toney Allen
Matt Barnes
Mike Dunleavy
Mo Williams
Nate Robsinson
Carl Landry
Nick Young
Corey Brewer
Earl Clark
J.R. Smith
D.J. Augustin
Devin Harris
Dorrell Wright
Tyreke Evans
Chris Andersen
Martell Webster
Dejaun Blair
Wesley Johnson
Al Forqua Aminu
Anthony Murrow
Greg Oden
Then possible others if they decide to Opt out
Trevor Ariza
Emeka Jokafor
Mareese Speights
Shawn Marion
Jerryd Bayless
Ben Gordon
If most of these guys land on any prominent team in the league, it could spell problems depending where they end up. Some guys will stay with same team out of loyalty and money but I see lots of chances for teams NOT STRIKING OUT IN FREE AGENCY
Can't tunnel vision Free Agency for CP3 and D-12 only, not surprised though, considering OP.
