According to his agent, Patty Mills will be joining the Spurs very soon. Reports the Experss-News: “Patrick Mills, the former Portland Trail Blazer who last played in China during the NBA lockout, has signed a contract with the Spurs and could join the team within the week, pending the resolution of work visa issues. Mills, an Australian national who could be in line for immediate minutes backing up Tony Parker, is eager to resume his NBA career, his agent said. ‘It shouldn’t be too much longer,’ agent Aaron Goodwin said. ‘There is a deal in principle. He just has to get a visa.’ Mills, 23, averaged 5.1 points and 1.5 assists in limited minutes during his first two NBA seasons in Portland. He is also a member of the Australian national basketball team coached by Spurs assistant Brett Brown. [...] The Spurs’ point-guard needs increased in Wednesday’s win over Minnesota, when Parker left before halftime with a tight hamstring.”
