Mavericks sign Dennis Smith

Dennis Smith Jr. has agreed to terms with the Heat, agent Daniel Hazan told Chris Haynes. Miami had been tracking the veteran guard throughout the offseason.

The Heat are signing guard Lester Quinones, Miami Herald reporter Barry Jackson reports, citing agent Scott Nichols. It's an Exhibit 10 deal, with Quinones competing for a two-way spot.

Norman Powell told reporters at Chicago's media day he isn't dwelling on trade speculation tied to his contract structure. Powell signed a two-year, $45 million deal with a team option for year two, a structure that could make him a deadline chip later.
