Lebron supposedly directed the Cavs to trade for Antawn Jamison because he thought a stretch four fits him better, so I presume he would value Love's game. I can see Cleveland being unwilling to give up Wiggins and Saunders being stubborn unless he gets Wiggins plus some.
If Boston still wants to get Love, they need to acquire a young SG/SF with 20 ppg and All-Star potential who is expected to be a starter next season to flip to Flip.
