PFW:Don’t completely block the “Randy Ratio” out of your memory, but remember head coach Mike Tice has emphasized ball control and the running game since he took over for Dennis Green. Sure, Moss, who set a personal best with 106 catches last season, is still a focal point of the offense and will get the ball often. But Tice wants to grind it with RB Michael Bennett first — a philosophy that also should benefit QB Daunte Culpepper — which is why he considers the team’s biggest offseason addition to be ORT Mike Rosenthal. The 6-7, 315-pound Rosenthal not only gives the Vikings one of the biggest offensive lines in the league, it allowed Tice to move Chris Liwienski back to right guard, a move Tice had been eyeing since Bryant McKinnie was drafted. “With that front five, Bennett will be hard for defensive linemen and linebackers to find, and with his speed, he can go the distance in a blink,” said one NFC pro personnel director. Short-yardage specialist Moe Williams will have a smaller role as long as Bennett has some early success in the red zone. Williams was re-signed more for his special-teams prowess and leadership than his utility RB skills.
