As to our pick and it's position, I give it 15-20 games before people start getting "injured". That should be enough time for them to get a feel of what they can do together. Even if we win 15 more games this season (and I don't expect us to), that puts us at 24 wins and probably secures one of the five worst records in the league. That should be a decent position to add a good talent.
Now, as far as the team we've got to look forward to watching the rest of this year, I look forward to seeing a quartet of Banks, Wade, Marion, and Haslem. I believe those four guys are likely to be an integral part of where we go next.
Banks is a very good defender who can get up and down the court quickly, and also shoots a very solid 38.5% from downtown. Marion is a stud, but how well he plays off of Wade will be quite interesting to see. Obviously, Haslem is going to fit from a player standpoint just perfectly. What I really like about those four guys, aside from their athleticism, is their ability to play defense. All of them do. Perhaps they can cover some of Mark Blount's deficiencies in both rebounding and defense.
As for their free agent prospects, even with J-Will and Davis expiring, they're not going to be under the cap. In fact, this year, they're paying the tax. They're about $8 million over. Once those two expire, they're going to have their MLE and LLE to use, and a solid pick. Of course, that cuts into their cap space the following year, as well. I don't know if they'll use them, or if they'll be intent on having every bit of cap space they can get their hands on when Marion expires.
If the Heat are looking for the quick fix, they'll trade either Williams or Davis (along with Smush

I have no clue what this team is going to do next year. Too many variables to predict. All I can say is that I'm really looking forward to seeing Wade, Marion, Banks, and Haslem playing on the same team, hopefully on Sunday...
