He's not going to take Mike Fontenot and turn him into Chase Utley or anything, but I think he will help with the hitter's consistency, quickly finding flaws in their swings and adjusting it before it turns into a prolonged slump. Will be interesting to see what he can do with Soriano and Fukudome, 2 hitters that have been known to fall badly away from their swing mechanics from time to time. \ gerald perry and von joshua were already considered among the best hitting coaches. rudy's contribution will be negligible.
