Joe Smith back to Cleveland? or Drew?

According to reports coming out of Oklahoma City, the Thunder reached an agreement to buyout the contract of forward Joe Smith allowing him to become a free agent and thus sign with any team.
Smith would be a natural choice to fill the hole left due to Ben Wallace's injury, but things aren't quite that simple.
Smith and Cavaliers forward Anderson Varejao share an agent in Dan Fegan.  That in itself clouds the situation, according to a league source who spoke on the condition of anonymity.
With Smith back on the team Varejao would certainly lose some playing time and given the fact that he can opt out of his contract at the end of the season, Fegan is unlikely to want to see the possibility of a big payday slip away.
Smith arrived in Cleveland just before the trading deadline last season.  He quickly became a team favorite and the Cavs didn't want to part with him, but had to to get Mo Williams.
LeBron James said after Sunday's victory over the Hawks, that he would welcome Smith back. 
The 6-10 Smith averaged 6.6 points and 4.5 rebounds with the Thunder this season but has seen his playing time vanish after a trade with the New Orleans Hornets was rescinded last month.
UPDATE: Things grew complicated when the Sacramento Kings released former Cav Drew Gooden just before the deadline Sunday.  The forward, who is currently has a groin injury, is another fan favorite.  Could it be the Cavs will have a choice of big men should they be unable to sign Smith?
The Kings got him in a trade from the Chicago Bulls before the trading deadline.  He spent almost four seasons here and averaged close to 12 points and more than eight rebounds.  This season he is averaging 13.1 points and 8.7 rebounds per game.
