FA's other than the obvious and possible trade targets

The names I have heard mentioned are Iggy, Granger, Pek, Al Jefferson, Martell Webster, Corey Brewer, etc as guys to upgrade the roster at the C and SF positions. Dell has stated that upgrading the roster is a priority so here am I looking around to see if there are other options that may work. There is not link stating that any one of these guys are actually on the Pels radar I was just looking at some guys that I want or I think would be a good fit or that is a young talent.


Center
Omer Asik 7'0" 255 (Rockets)
3 years/25 mil
-he's 26 and I put him up here because I think the Rockets move him if they get Dwight

Enes Kanter 6'11" 267 (Jazz)
3 years/4.3 mil
-young center (21) don't know much about him but he makes 4.3 mil a year

Larry Sanders 6'11" 235 (Bucks)
2 years/1.9 mil
-24 years old saw he made the USA basketball minicamp roster

JJ Hickson 6'9" 242 (UFA)
-24 years old undersized for a C but can rebound well and made 4 mil last year

Timofey Mozgov 7'1" 250 (RFA - Nuggets)
-I know nothing about this guy but ESPN had him ranked 21st out of top 30 he's 26 years old and made 3 mil last year

Small Forward
Gordon Heyward 6'8" 210 (Jazz)
2 years/2.7 mil
-young good shooter (23 years old) 6'8", makes 2.7 mil a year and put up 14 points a game last year

Tyreke Evans 6'6" 220 (RFA - Kings)
-been talked about before but the Kings have an excess of guys so we could get him cheap he made 5 mil last year he's 23 years old

Ersan Iiyasova 6"10" 235 (Bucks)
5 years/8 mil
-he;s 26 can rebound well, good shooter, plays pick and pop well, and he looks like James Franco


this is just my take I don't know how high GV's value is but I think teams would like a guy who can average 9 assists a game...anyway acting like a GM is just a hobby for me so take all this with a grain of salt but its fun to speculate
