There's no way to answer because we don't know what kind of team the Cavs would have with Lebron right now.
This Miami Heat team with Bosh and Wade is tied 1-1 with the Thunder. No way do the James' led Cavs from whatever year ('07?) even stand a chance against OKC.
To clarify, it would be the 09-10 Cavs team (Mo Williams, Anwant Jamison, Varejao) without Kyrie Irving for obvious reasons...
That's almost the same as the '07 team. So I think they still wouldn't have a chance. Plus, they wouldn't have high picks at all, since they'd probably be competitive every year.
