5:35pm: The team has indeed waived the five players, Marc J. Spears of ESPN.com confirms (Twitter link).
SATURDAY 5:25pm: The Mavs will waive Jonathan Gibson, according to Tim MacMahon of ESPN.com (ESPN Now link). MacMahon adds that Dallas will opt to give Dorian Finney-Smith its 15th and final roster spot, meaning the team will also waive Kyle Collinsworth, Keith Hornsby, Jaleel Cousins and C.J. Williams.
Gibson’s release is particularly surprising because his minimum salary deal is fully guaranteed for the upcoming year. Dallas also chose to keep Nicolas Brussino, whose contract became guaranteed on Thursday.
Brussino and Finney Smith are both forwards and the Mavericks appear to be looking for upside and versatility in the players they keep at the end of their bench. Gibson, who turns 29 next month, doesn’t fit that profile. He can score the ball, but he has limitations on the defensive end.
