Ray Allen will replace Mario Chalmers in Miami's starting lineup during Sunday's potential elimination game in San Antonio. Chalmers' terrible play is at the root of coach Erik Spoeltra's decision, but Allen has copious experience in pressure games and he's averaging a respectable 11.0 points on 48.5 percent shooting in the series. He's a capable ball-handler and the Spurs need no reminder about his 3-point prowess, but Allen's offensive contributions won't mean much if Miami doesn't find a way to lock down defensively.
