The Bucks agreed to terms on a three-year, $24 million contract with Mayo last week. But thanks to a series of moves that general manager John Hammond has in the works, the Bucks had to wait until Saturday to make the contract official.
The 25-year-old Mayo averaged 15.3 points for the Dallas Mavericks last season, and he should have no trouble finding shots in this new-look Bucks lineup.
Hammond executed a sign-and-trade deal with the Suns and Clippers that sent J.J. Redick to Los Angeles and volume shooters Monta Ellis and Brandon Jennings could soon be following Redick out the door in Milwaukee.
Ellis is reportedly set to join the Mavericks in Mayo's place and the Bucks have signed restricted free-agent point guard Jeff Teague, who played for new coach Larry Drew in Atlanta, to an offer sheet. The Hawks matched the offer Saturday, sources told ESPN.
Ellis and Jennings were far and away the leaders in scoring and field-goal attempts for the Bucks last season, meaning Mayo should get plenty of opportunities to show he is capable of carrying the scoring load for an entire season.
After spending his first four seasons with the Memphis Grizzlies, Mayo hoped to cash in big on the free-agent market last summer. But the money dried up quickly across the league, and he wound up taking a deal with the Mavericks that paid him more than $4 million last season.
He opted out of his two-year deal to test the waters once again, and for a moment it appeared that he could be stuck on the outside looking in for a second straight summer. Mayo's name was near the top of the list of available shooting guards, a list that also included Redick and Ellis from the Bucks and Kevin Martin from the Oklahoma City Thunder.
Mayo was inundated with attention when the market opened on July 1, speaking to the Timberwolves, Clippers, Bucks and several other teams. The Clippers pulled off a sign-and-trade that brought Redick to Los Angeles and the Wolves did the same to land Martin from Houston. With the Bucks getting nowhere in talks to bring Ellis back, Hammond shifted his sights to Mayo.
In Milwaukee, Mayo will immediately become an offensive focal point like he was in the first few months of last season in Dallas while star Dirk Nowitzki sat out with a knee injury.
The Bucks added steady veteran point guard Luke Ridnour in a trade with the Timberwolves earlier this week, but still were looking for the kind of player who can get to the basket and score in transition.
Mayo seems to fit that bill. He shot nearly 45 percent from the field, which was the second-highest mark of his career, and showed flashes of potential to be a go-to scorer during the early part of last season while the Mavericks waited for Nowitzki's return. He averaged 20.9 points and shot 52.9 percent from 3-point range in the first month of last season, including a 40-point game at Houston on Dec. 8.
Mayo shot a career-best 40.7 percent from 3-point range last season for the Mavericks, but his production dipped noticeably as the season wore on.
The Bucks have Ersan Ilyasova in the front court, but there are few offensive threats on the rest of the roster. Larry Sanders emerged as one of the best defensive players in the league last season, but his offensive game is still raw. John Henson showed some promise as a rookie last year, but likely is not ready to assume a major role yet. Carlos Delfino and Zaza Pachulia have also agreed to terms on deals but are role players.
