LA is not a better team than Boston. Lets not forget that Boston has been winning, after having played five more games, and having key starters hurt. Peirce, Perkins and Rondo all have injuries. It has been proven that Bostons starting eight, and thier bench are more talented. Boston can, and has, rode thier bench for extended periods of time. Even won games with them. On the flipside, whenever Jackson tries to ride his bench ( like he did vs the spurs), the lakers start getting mashed.
I guess you could say on paper the lakers seem more talented, but when it counts, Boston has proven they have it.
