Then there’s Minnesota running back Adrian Peterson. He tore the anterior cruciate and medial collateral ligaments in his left knee on Dec. 24, 2011 and had surgery six days later. He was back for the Vikings opener on Sept. 9, less than nine months later, and ran for two touchdowns in that game. He led the NFL in rushing with 2,097 yards, just nine short of Eric Dickerson’s NFL record.
So Rivers is hopeful.
The NBA season usually starts in late October, giving Rondo about nine months to recover.
‘‘We've got a guy in the NFL that we can look at in Adrian Peterson,’’ Rivers said, ‘‘and whatever he did, that’s what we want to do. Because that was amazing. And that’s what Rondo will do.’’
