OK, here goes......
I broke down the Celtics/Cavs Record according to "5 points swing" and "10 points or more swing".
I also calculated and factored in SOS (at the time each team faced their opponents and overall record as of 12/21).
Here are the results:
Games decided by 5 points or less
(C's average margin of victory +4ppg/7games)
C's vs Cavs 10/28 (Won 90-85) 1-0 +5 Cavs (0-0, 23-4)
C's vs Rox 11/4 (Won 103-99) 2-0 4 Hou (3-0, 18-9)
C's vs ATL 11/12 (Won 103-102) 3-0 1 (6-0, 17-10)
C's vs MIL 11/15 (Won 102-97) 4-0 5 (5-5, 13-16)
C's vs CHL 11/29 (Won 89-84) 5-0 5 (5-10, 9-19)
C's vs IND 12/7 (Won 122-117) 6-0 5 (7-12, 10-17)
C's vs ATL 12/17 (Won 88-85) 7-0 3 (15-9, 17-10)
28 (41-36 @ 0.532)(90-75 @ 0.545)
Cavs Record: 1-2, average margin of victory +1.333 ppg
vs Bos 10/28 Lost 85-90 0-0, 26-2
vs Ind 11/07 Won 111-97 1-2, 10-17
vs Atl 12/13 Lost 92-97 13-9, 17-10
14-11 @ 0.560, 53-29 @ 0.646
The Celtics are undefeated, a perfect 7-0 in games decided by 5 points or less. The Cavs are only 1-2 in games decided by 5 or less.
Hollinger believes that "close games" are more along the lines of luck or good or bad fortune. He basically doesn't put much value on winning close games, or maybe he just puts too much emphasis on winning blowout games.
I can see his point, good teams should blowout BAD teams, but what if good teams face other good teams? Shouldn't the games be a lot closer? (YES, duh!)
Bottomline here is, with the current data, the Celtics faced above average competition based upon the 0.532 current record and 0.545 overall record to date: 12/21/08.....and they still went 7-0.
The Cavs on the other hand faced 3 teams and lost twice, but their SOS (0.560 current, 0.646) was higher than the C's.
What this data tells me is that the Celtics faced decent competition and prevailed. The Celtics were better and so they won in the end.
The Cavs faced tougher competition and lost. The teams that beat the Cavs were better than the Cavs.
Now let's look at games decided by double digits......

OK, clearly the Cavs are showing they can do well against poor competition, based upon the current SOS 0.402, but it makes sense that good teams would "destroy" bad teams, doesn't it?
But the Celtics clearly show that they can blowout "good" opponents, based upon the current SOS of 0.515, both overall SOS are virtually the same around 0.430ish.
In conclusion, John Hollinger puts too much stock into blowing out the competition.
Generally, good teams will blowout bad teams, more often than not, but when good teams blowout other good teams or when good teams beat other good teams by smallish margins, those good teams should be acknowledged and recognized for those efforts and achievements.
The Cavs are a good team, but they are not better than the Celtics.
