Agree on all fronts, although when you tick through movement data on baseball savant it is interesting how varied the movement profiles are for 4SFBs and 2SFBs across the league.
Bradish added a 2-seam FB towards the end of the season to great effect, so hopefully GRod will experience similar success.
It seemed to me (purely anecdotally) that he began to have success when he was able to locate his FB consistently at the bottom of the zone, and pitching up with it only selectively in strikeout counts. Earlier in the season it seemed like every FB was up, intentionally or not.
