The defensive profile of a player has always been important to scouts, but recently the public’s understanding of defense has expanded.  Advanced stats and video analysis have allowed even casual fans to break down defensive plays.  Even so the baseball world is only starting to scratch the surface of defense and its value.  In terms of raw tools defense is a component of speed, arm, and glove, but instincts and coordination also play a big park in defensive success.  Rather than break down the best of each across the system I am going to break down the defensive profiles of major position groups in terms of the players that best exemplify that tool for that position.

Catcher defense is the farthest behind in terms on analysis because it touches so many part of the game.  We can measure pure arm strength by pop times, and a good throwing catcher will limit how much opponents even try to run.  Tommy Joseph has a cannon of an arm, it is at least a plus tool, only limited by his ability to get moving his arm has accuracy to go with the pure power.  Catcher receiving is often underrated and as fans we often look at their ability to block balls in the dirt and out of the zone, but a catcher who is quiet in the zone can make a huge difference.  Cameron Rupp offers pitchers a huge target and a quiet glove; he is not an elite receiver but he is very solid behind the plate.  The whole package of catcher defense can be an incredible thing, a catcher combining both the receiving and arm can be worth many wins in value without hitting.  It is not a complete package yet but Deivi Grullon combines an arm that could be plus plus by the time he is fully mature and he is a work in progress receiving but the feel is there to have a plus glove, giving him a near elite defensive profile.
