Looking ahead at the NBA playoffs second round

Boston vs. Milwaukee. Philadelphia vs. Toronto. Houston vs. Golden State. The first round of the NBA playoffs had plenty of emotion — just ask Damian Lillard and Russell Westbrook — but it was short, with very possibly only one series going at least six games. The second round? That's not going to be so quick, and it is filled with even matchups that present a lot of questions. Is this the Rockets' year? They have the formula, can they execute it? The Bucks were the best team in the regular season, but can they carry that elite level into the second round against Boston? Is Toronto the team to beat? Kurt Helin of NBC Sports welcomes in Keith Smith of Yahoo Sports/Real GM/Celticsblog to look ahead at the second round, and even talk a little about what is next for Oklahoma City.
