The Cleveland Cavaliers are firmly in the lead to acquire Kevin Love but the Chicago Bulls are making a renewed push to get into the trade mix for the All-Star power forward, according to sources close to the process.

Sources told ESPN.com the Cavs are increasingly optimistic that they are progressing toward a trade framework that the Minnesota Timberwolves will accept in exchange for Love to pair him with his Team USA teammate LeBron James.

Cleveland's offer, sources said, would be headlined by No. 1 overall pick Andrew Wiggins, 2013's No. 1 overall pick Anthony Bennett and a future first-round pick. At least one more player might have to added to the package to satisfy NBA trade rules.

Sources say that the Bulls, though, have re-entered the race and would appear to be the biggest threats to the Cavs, thanks largely to the Golden State Warriors' resolute unwillingness to add longtime Wolves target Klay Thompson in any deal.

Although the full extent of the Bulls' offer wasn't immediately known, it is believed Minnesota would seek a package from Chicago featuring forward Taj Gibson and defensive ace Jimmy Butler in addition to other assets. The Bulls shelved their Love interest while trying to sign Carmelo Anthony away from the New York Knicks but, according to sources, have re-emerged as contenders.

ESPN.com reported as far back as May that Golden State and Chicago were prime destinations that interest Love, who holds more than the usual sway in this process because he has the ability to become a free agent next summer.
