10:27pm: Tim MacMahon of ESPNDallas.com reiterates our contention that Harris will likely spend a lot of time at shooting guard next to Calderon in the Mavs' backcourt. MacMahon notes that Harris spent half his time next to Jeff Teague at shooting guard last season with the Hawks, so the transition won't be difficult. Acquiring Harris also allows the Mavs to bring their rookie guards, Shane Larkin and Gal Mekel, along more slowly.
8:04pm: Although the deal can't be made official until Wednesday when the NBA's July moratorium is lifted, ESPNDallas.com's Tim MacMahon says the Mavs struck a deal today to bring Devin Harris back to Dallas for a three-year deal in excess of $9MM. With Harris' and Jose Calderon's deal, the Mavs have solved their backcourt problems from last year.
The 30-year-old Harris averaged 9.9 PPG and 3.4 APG in 24.5 MPG during part-time starting duties with the Hawks last year. But Harris primarily played as the off-guard when Jeff Teague was in the game at the same time. This might be how the Mavs choose to use him in conjunction with Calderon.
Harris is repped by Excel Sports Management, as shown in the Hoops Rumors Agency Database.
