Randy, sorry if I made that implication. Just on salaries alone it would have to be Zach and DA at least, and probably more to make both deals work. Zach is in the range of $1.5 to $2 million and DA is at about $7 million, and both Allen and Pierce are at $12 + or -. Portland would have to add another 1 to 2 million in salary on top of Zach and DA to make it work.
On talent if I was Seattle or Boston I would want at least Zach and DA, and then however it works on the remaining roster fodder. Zach has lots of potential, but I wouldn't trade a star like either of those 2 straight up for Zach. Zach has to prove himself some more, and he needs to improve some more before a 1 for 1 would be in the cards. Zach is finishing his 3rd year, and he has one more year left on his rookie contract. After next year he would be able to get a deal like Elton Brands deal with Miami that the Clips matched. If he has another year like this and improves then a one for one might be in order, but again salaries wouldn't match. If Portland got either Allen or Pierce they wouldn't have any need for DA, so I would expect him to move on.
As far as Lewis, I like him, and if Portland got him that would be great. My only point is that at 6-9 and 255, and being a power player, those are highly desirable skills. There are more players similar to Lewis than are similar to Randolph. Right now Lewis is a better player, but in 2 years I think Zachs upside potential is such that you should get more to take that risk. This goes back to Jermaine. We gave up to quickly on him, and didn't get anywhere near the value we should have for him. He is a big guy, with lots of upside, and there just aren't very many of those around.
Lewis and Brent Barry would be good as well, though I am a little concerned with getting Barry at 31. I love watching Seattle play with those 2, plus Allen and Radmanovic. Lewis and Barry for Zach and DA would cuase me to do some serious pondering.
