Barring a monumental collapse over the final six games, the Spurs are relatively certain to finish either first or second in the Western Conference. Who they might play in the first round is not as clear. With the bottom of the West playoff bracket a logjam, Spurs coaches have begun preliminary preparations for a potential series against several teams. “In the West, it's kind of hard to figure out, so you prepare for several,” coach Gregg Popovich said. “Bit by bit, slowly, I'm sure that process is done for all the teams.” If the playoffs began Friday, the Spurs would face Memphis in the first round, but the matchup changes daily. If not the Grizzlies, the Spurs are likely to begin the postseason vs. either Dallas or Phoenix. “I think it can change like 50 times,” point guard Tony Parker said. “Every day it can change.” The Spurs are 3-0 this season against Dallas and Memphis, and 2-1 against Phoenix. Inadvertently, they will have a hand in who they might face. The Spurs play each of those teams in a four-game stretch beginning Sunday against the Grizzlies. “It doesn't matter who we play. It's going to be a great team regardless,” Parker said. “The West is loaded. Each team creates different problems.”
