In the entire history of the league there have been something like 3 champions that didn't have a top 5 player on them. Those are the last Spurs title, the last Pistons title, and the Sonics/Thunder's only title. That's basically it. The Spurs had 4 HOFers at varying career points (TD old, Manu old, Parker in prime, Leonard on rise), the Pistons were incredibly deep with 4 or 5 All Star level players including the 3rd best defensive big/rebounder of all time (only Russell and Rodman eclipse Wallace in those), and the Sonics had 2 HOFers the rise (Sikma, DJ), a multiple time future All Star (Williams), veteran depth, and won in basically the weakest season in the sports history (you know right before Bird and Magic entered the league).
Boston doesn't have a top 5 player. Boston doesn't even have a top 10 player. Boston has 2 All Star (and possibly All NBA) players, a clearly injury hampered former All Star, and basically nothing else. This idea permeating this board that this team was going to compete for a title this year was just strange to me. There is a reason so few teams win titles without top 5 players. There is a reason teams without top 5 players rarely compete for titles for more than an odd season or two. In basketball, you quite simply, need a top 5 player to really and truly compete for a title. If you don't have a top 5 player, then you aren't really going to compete year in and year out. It just doesn't happen.
