They could get aldrige and roy if they traded him this year but not next.
Cleveland will be devastated by his loss but come on roy and aldridge would be more than excellent players in return plus knowing you could build a future around them is a good thing. Lebron is a big question mark and its funny how cavs fans still believe foolishly he will stay with the team forever. (he is gone 100 percent by 2010)
Personally if i were the cavs management this is what i would do.
1)try to have talks with lebron about his future with the cavs and where he stands.
2) If he seems 100 percent disinterested in coming back, see how the cavs do against elite teams like the celts, lakers and denver this year before the trading deadline. (see if cavs have improved from last year which i doubt)
3) If cavs are over 500 against those 3 or 4 elite teams then keep lebron, if not then make a trade. (gives you a good idea how the cavs could handle them in the playoffs)
4) two teams i see that could afford to give cleveland the most are GS and LAL. GS = Ellis(will be back and gs is not too happy with him), biedrins, stephen jackson and a 1st round pick for lebron
LAL = Kaman, al thornton, eric gordon and 1st round pick for lebron, ilgauskas and 2nd round pick
Doubt portland will give up aldrige and roy even for lebron
The best thing about such a trade like this is that the cavs can just have a peace of mind and move on. It must be uncomfortable over there right now. Yeah lebron brings in merchandise sales , seats but the big question is can you win it all with the team he is surrounded with now?? If not for the next two years then instead of losing him for pretty much nothing and signing a high priced FA not as good as lebron, a trade right now should be explored
