Alston is out for game 3 so we'll see Anthony Johnson starting in his place. Also, it sounds like Courtney Lee is going to play for the first time in this series. So we'll be seeing a different look from their backcourt tomorrow.
Third Quarter Collapse breaks down the impact of these changes:
Let's clear the air first, though. Johnson is a good defender, but he can be exposed defensively when paired up against a quick point guard like Rondo. A.J. lacks the lateral quickness to keep Rajon in front of him, which is a problem. That's why Lee is anticipated to guard Rondo tomorrow some of the time if he ends up playing, because he has the athleticism, size, and speed to make it potentially difficult for Rajon to operate offensively.
