Strength is great later on with your WR as the levels go up - moral stays up, break tackles will soar, you won't be striped of the ball, etc.... breaking a tackle can mean the difference of 0 yards after catch and forcing a miss tackle going all the way to a TD... 48 and over would be fine for a speedster... its not a major or minor attribute, but it can definitely help your later on leveled WR...
