I like David West's contract(kind of, not really)and the fact that his jumper is the epitome of consistent.
However, I've read multiple connected people talk about how CP3 doesn't even like David West. He can't shoot the three, and he has a tendency to disappear and struggle immensely against bigger fours and length really bothers him. He struggles to create for himself although he is crafty in the post at times. He can get to the line a bit as well, but nothing amazing.
I'm going to take Jamison. Even though at times he can be streaky from beyond the arc(he is less streaky inside the arc), I'll take the risk. He's also older, not quite as long of a contract but close. That has to be taken into consideration.
For me, I'm going to still go with Jamison. For one, I think it'll take less to get Jamison. I think we can get Antawn with Z and maybe a pick once Washington decides its time to blow it up. David West is going to cost J.J. Hickson, and we may have to take on either Peterson or Posey as well(Posey might not be a horrible thing) and I also thing NOH is less likely to agree to buy Z out and let him return, they could use a big skilled body who can shoot and hit the glass for 20 minutes a night...Washington has no use for him.
Now for their games...they're both of similar size. Jamison might be a bit longer, West has some more bulk. West may or may not be better defensively. He can't guard "stretch-4"s very well, and has trouble when people get physical with him or when they just plain have size/strength on him. Jamison doesn't guard anybody, but it's less about ability and more about not giving a shit. I think we could mask him efficiently, much like we did with Mo. not to mention his offensive role would be less prominent, so he'd have more energy for the defensive end.
Now like I said, West gets really frustrated by physical or long/strong defenders. Jamison not so much, Jamison is very crafty with his moves and has a plethora of ways to put the ball in the basket...West has really just got a jump-shot and a mediocre post-game.
West should be a better ebounder than he is, although he has been at time.s.he's streaky in that area. Jamison is always a pretty solid rebounder and tends to do well on the offensive glass(particularly tipping in his own misses).
Ultimately I think Jamison is a guy we can give the ball to and have go to work in important games/situations. West isn't, he's a guy who can come through if LeBron goes to work for him and sets him up in crunch time.
Give me Antawn.
