I'm gonna be honest today I tried testing something with the BRAND NEW Sean Taylor (ST21) and I'm very perplexed to wether or not this ability even works....
THE TEST: I threw several balls from various styles (BULLET,LOB, TOUCH PASS etc.) It was a inside post pattern with 94 OVR Jordan Reed down the seems where Sean Taylor could make most plays on... out of the several passes the ability DEEP ZONE KO lit up one time therefore not getting a increased reaction on a late breakup....but pick artist constantly lit up every single time Sean was in position to get the ball....went to abilties.fyi and I will say this whole heartedly....how is this deep in and deep out together if it doesn't give out a improved reaction to the ball inside and outside the hash marks from the other respected abilities?
EDIT: Yes, I have seen Zan's Guideline of zone abilities but he never throughly explain this ability which is a clear discrepancy.
