I doubt there's any way to get Beasley, but he'd be interesting. I'm not really sure why people were so disappointed with him, he came and and showed he was someone who could score a bunch in non-starter's minutes. When Ben Gordon does that as a rookie he's 6th man of the year, when Beasley does it he's a disappointment?
Obviously he's got a lot to work on, but we excuse Rose's defense and lack of shooting range as him being a rookie, I don't see why you'd be too down on Beasley. Given Bosh is nearly 5 years older than him, and Amare over 6 years older than him, I can see the appeal for some people. That said I doubt it matters because two players rarely end up playing on the same team together for a decade. Bosh and Amare are both plenty young enough so I'd take them as known quantities.
