I think we have to be concerned. if you had added a good big man scoring threat, which i belive would allow LBJ to work both the drive and kick to a shooter and the drive and dump off to a big who just lost his defender option, id be a lot more concerned.
righ tnow, i still see the cavs as having the same weakness we exploited during the playoffs. without a legit big man scoring threat, you can make LBJ take jumpers in half court, since no one needs to fear the pick and roll with B.Wallace or side show bob.
in short, you lack a "scoring big" ( i know Z can score, but he's a jumpshooter at his deadliest, im talking like a leon powe paint guy) which means your shooters HAVE to be hot.
but, yes im concerned. right now i think we have 3 legit threats. Detroit, clev, and philly.
the magic and raptors may get upgraded if they show me something.
on a side note: good to have you back, mac.
