Boston has been very healthy this year. I think Minott is the only guy who wasn't available for every game and he missed just 1. They are 6-7 but 3 of the wins have been the Wizards, Pelicans, and Grizzlies, plus they've split with Orlando and beat the Sixers 1 in 3. Cleveland is a legit good win, but they've lost to a bad Utah team and every other good team they've played i.e. the Pistons, Knicks, and Rockets and 2 of those 3 were complete beat downs.
So with full health they generally are going to beat the bad teams but lose to the good ones. That is with full health. They won't have full health all year. Those type of teams are generally more like 35 win teams over the course of a season. The next 4 3-1 is possible as they host the Clippers then are @ BKN, home with BKN in the tourney game, and then the Magic come to town again for ther 3rd game of the year. After that though they have a pretty tough stretch i.e. DET (tourney), @ MIN, @ CLE (2nd of back to back), NY, @ WAS, LAL (btb), and @ TOR before the tourney break. That is a tough 7 game stretch. I think that will give a fairly clear picture of the type of team this is.
