Should the Vikings take a Running Back at 7-top three RB's

Here's an evaluation of the three running backs, projected to go in the Top 10, this year.

Ronnie Brown-

Strengths: Great size, speed, and power. Can catch the ball out of the backfield. Can move a pile. Good blocker on passing downs.

Weaknesses: Lacks great elusiveness of cutting abilty. Doesn't go from 0 to 60 as fast as some would like.

Cadillac Williams-
Stregths: Tough, elusive runner. Great vision, and patience. Good speed.
Weaknesses: Durablity, not a great receiver. Like teammate Brown not a great accelator.

Cedric Benson-
Strengths: Powerful, physical back. Best intial accelator of these three. Good patience and vision. Hits holes hard. Great balance, and body control. Devloped as a receiver.

Weaknesses; Not great speed, and some have questioned his dedication to football. He has also had run-ins with the law, including for Marijuana position.
