A future Heat 1st rd pick could have some really good value. There are some major questions for the team this off-season. A owner that is against the luxury tax bill and will continue making decisions because of it (amnesty of Miller), the opt out option of James, Wade, and Bosh, the free agency status of Allen and Chalmers, the impending Battier retirement at the end of the year (he's been giving plenty of not so subtle hints), Wade knees, and the rumor that Dallas will be going hard after Bosh this summer (he's from Dallas and could be growing sick of such a reduced role - 14 ppg, 6 rpg, 28 mpg, 10 fga this year).
While that team is great now, but they are an older team and aren't free of question marks. There future isn't as bright as some may think and this could cause a future 1st to have some legitimate and unexpected value.
