Q: I hope they don't give Mario Chalmers a drug test. Who is this guy? Where has he been all year? -- Chet.

A: He is a guy who is playing to his strengths, mainly converting timely shots, keeping mistakes down, and understanding most of his work comes off the ball. Even Thursday, while filling the scoring column, he went without an assist. But the prime reason he has thrived this series is there has been very little in the way of a defensive challenge. That will change soon enough, when Chalmers will have to work on both ends.
