Miller is a perfect triangle player. He has guard skills to compliment his forwardesque scoring style. Check his floor game numbers or the scouting report. The guy can handle AND pass (has spent time at PG for the depleted Grizzlies a few years back).
Yes, he's also an underrated defender. Most people see a white guy and they just assume he doesn't have athletic tools. He's extremely long and relatively athletic. He won't wow anyone, but he's a full notch above Vlad when you pull out the hop, skip, jump, and run measuring sticks.
However, Miller is soft as hell. This guy disappears in the crunch and his jumper follows him. He gets pushed around at times despite the best rebounding numbers of any "shooting guard" (though he's not really a guard).
In some ways, he's the perfect fit, but, in my opinion, he is the antithesis of the solution to our problems. He makes us weaker and softer on the inside and he's not much of an improvement over Odom, if at all, when it comes down to crucial moments.
In the past, I would have liked this trade, especially because it would have involved one of the Memphis PGs, but the Lakers absolutely have to get a legitimate big man in return to pull the trigger on a Miller/Odom swap.
