I really don't think we'll get blown out much in the playoffs. Since Feb 1st (my semi-arbitrary split between Bad Cs and Good Cs) we've only been beaten by double digits 3 times - Cleveland, SA, and Clippers. And only the Cleveland game was really a blowout, with the other 2 being by 12 and 13 points. We're not so great at beating top teams, but good at staying with them.
I wouldn't be shocked if we got blown out once out of 4 losses, but I think it's more likely our losses will be of the "scrap all game, hang in within striking distance but get overwhelmed down the stretch" variety.
