There are more than 30 million reasons for Dwight Howard to re-sign with the Lakers this summer, but as is often the case with Howard, he hasn't made a decision on his future yet. According to Sam Amick of USA Today, Howard is "torn" between the idea of re-signing in Los Angeles or pairing with James Harden in Houston and signing with the Rockets.
This isn't the first time in the last several days that we've heard Howard is intrigued by the Rockets. A report over the weekend indicated that the All-Star center was showing interest in both the Rockets and Mavericks, though the report classified the Lakers as the frontrunners. A separate report since then classified Howard's relationship with current Lakers coach Mike D'Antoni as somewhat strained, so if D12 decides to sign where he'd be happiest, it's not hard to make the case that'd be somewhere besides L.A.
We're still several weeks away from July 1st, when teams can officially make pitches to Howard and other free agents, so I wouldn't expect Dwight to make his final decision before that point. When free agency opens, the Mavericks, Hawks, and perhaps the Cavaliers are expected to join the Lakers and Rockets in pursuit of Howard.
