I think it makes more sense then some of you are giving it credit for. This doesn't necessarily mean we are going to give away AL just to sign Lee. I like the idea, especially and specifically if we end up pulling off some sort of Al for Gay swap. Lee should fit in better than Al.
Just because they are both white and elite rebounders doesn't mean Lee and Love are all that similar. Love is a skilled big who can facilitate the offense. Lee doesn't demand the ball and is happy getting his points by crashing the boards and running the floor. Lee does have an improving offensive game and can be used in pick and rolls, which is really just a bonus since we'd throw the ball into Love and Darko more anyway.
Lee and Love is quicker and more athletic than Al and Love. Something Lee never had in New York is a shot blocker like Darko to watch his back...Oh wait that is exactly what he had, but D'Antoni is completely oblivious to any and all things defense

.
Lee is a real stand up guy who plays hard every night. I think he might be willing and comfortable coming off the bench even. I actually think this is a role he could excel at with his high energy. I know what you some of you are thinking... You don't play a guy 10+ million or so to come off the bench. I don't buy that. Starting is for high school. I think we can realistically manage the minutes between Love, Lee, and Darko with all 3 nearing 30 minutes give or take on a given night depending on hot hands and matchups.
Lee is a better fit next to Love & Darko, in our offense (both uptempo and half court), and with Flynn/Rubio. Hypothetically, if we did manage an Al for Gay (or really any wing of equal value) and then signed Lee we would have significantly upgraded our wing positions with the additions of Wes, Web, and whoever we'd acquire for Al... plus, we'd maintain a very strong trio of bigs capable of pounding teams on a given night. Not too mention the newest of the 3 bigs is actually a better fit than his predecessor.
