I have actually spent a good deal of time thinking about this, and it doesn't make me too happy. The Cavs will almost certainly get one really good player in a trade, and could very well get two. The guys who I find especially trouble are in this order.
1. Mike Miller
2. Michael Redd
3. Antawn Jamison
4. Brad Miller
The reason I have Miller slated at the top is that he is the guy who would be the most useful to the Cavs. They would not have to mess with theuir starting lineup at all, as he is a former SMOY, and can play 3 positions for them. The dude is 6'8", a pretty good athlete and a great shooter. They could play big with him at the 2, and small with him at the 3 with LeBron at the 4 (which is what my reasoning revolves around).
Redd would be a huge addition, but he and Mo wouldn't make for much of a defensive backcourt. I think that Rondo and Ray would pummell them, whereas as Delonte actually plays really good defense at the 2 and has been a great fit in Cleveland... which many of here long thought that he would be, even when he played for us. Still Redd is a primetime scorer and a floor spreader.
Jamison is troubling because he is a good rebounder and a good shooter for a guy of his size. They could play him at the 4, keep LeBron at the 3, and give teams fits. They could even go micro with Jamison at the 5 and LeBron at the 4, provided that one of the other two gets picked up. That would not be fun to guard.
Miller is a good shooting vet who can still play. He's also a great passer. I just wonder how he would be used, because Wallace is actually thriving this season as a starter. You really wouldn't want to bring him off of the bench, and he isn't going anywhere.
The problem for us, and everyone else, is that if they picked up two of the top three you could literally surround LeBron with elite shooters at every position at critical moments of games, making it nearly impossible to effectively double team him. He is such a great passer that he would make any team pay for doing so, yet he is such a great score and athlete that stopping him man-up is nearly impossible. They could very well be able to get both Miller and Redd, and that would a very bad thing for us, as it wouldn't mess much with their teamchemistry, especially Miller. Even Miller, alone, would be a major blow to our Title hopes.
