The Toronto Raptors starting power forward position is open for competition with Amir Johnson's departure via free agency to the Boston Celtics. Patrick Patterson may have the inside track to winning that spot. From Doug Smith of the Toronto Star:

"In an NBA career that spans five seasons, Patterson has played in 333 games but started only 65, including 11 in a season and a half with the Raptors. But barring major changes between now and training camp, the Raptors’ starting power forward job, once filled by Johnson, is Patterson’s to lose. The 26-year-old has never started a season as a club’s No. 1 power forward and he says he is embracing the chance. But he’s still ready to compete for the job. ... Three weeks ago the Raptors signed Luis Scola, a defensive-minded veteran who should share time at power forward with Patterson. Scola has already shared wisdom with Patterson, who says the Argentine was a mentor when they were teammates in Houston."

Heading into training camp, Toronto's PF depth chart might look like this: Patterson, James Johnson, Scola, Ronald Roberts Jr.
