A nice comparison of the Bulls vs the Cavs using the four factors matched up against each other can be found here. The key reason as to why the Bulls have little hope is here:
Now, the bad news...and that means we have to look at Bulls offensive (pun) statistics.
Eff eFG TO% OREB% FT/FG Bulls Offense 103.5 (27) 47.7 (28) 15.2 (15) 26.6 (16) 21.7 (21) Cavs Defense 104.1(7) 48.2 (3) 13.9 (T26) 22.8 (2) 21.8 (13)
This is the thing about facing the best team in the league. They can
be good at both offense and defense, a concept us fans in
mediocrity-land don't believe is possible.
The Bulls stand a chance against the Cavs offense and holding them to a reasonable amount of points. What they don't seem to stand a chance on is defense where the Cavs have one of the better defensive teams in the league against our wretched offense.
Matt concludes that the Bulls will need to win by hoping Rose/Noah have the best series of their lives. Hard to argue with anything there as depressing as it might be.
Matt picks the Cavs in five, and I've already noted in my overall breakdown that I agree.
The Bulls can win the matchup at PG, and they can win it at C, but they aren't dominantly better at either position. They might even win the matchup at SG. So how can the Bulls win three of five starting matchups and have no chance? They're barely going to win any of them, and the gap at SF and PF is huge. The gap with the bench is mammoth.
The Bulls will have no answer for LeBron James. Luol Deng has been serviceable in the past, but he's playing on one wheel right now, and couldn't even stay with John Salmons on defense. Tyrus Thomas has done a nice job on James at moments, but he's gone.
The Bulls will have to hope rookie James Johnson or Kirk Hinrich can slow James down, and the odds of either are frighteningly small. On the other end, Derrick Rose is a better player than Mo Williams, but he'll be playing through double teams all game long with a closed off lane while Mo Williams will get a ton of uncontested jumpers. The end result might show Williams having a better series.
If the Cavs can get back on defense to limit Noah's fast break points, then the Cavs stand a very good chance of controlling him on the offensive glass, and you never know which Kirk Hinrich is going to come to the stadium any given day. When the Bulls play at their absolute peak, they're going to be good enough to beat the Cavs on an off day.
That combination might happen once this series, it might not happen at all, but it's not going to happen four times.
