For me, FS is a spot that more and more is needing speed. More speed than all corner spots outside of field CB. Boundary corner needs length and size but generally has help over the top. Nickel corner relies on quickness and tackling ability. Generally they only carry the seam to a certain depth until the S comes into play.
FS needs huge speed to play cover-3, cover-2, cover-1 in today's game of spread offenses.
We have recruited a bunch of box S types who are all hitters. It's ok to be a bit slower at the LOS, but in a cover-2 or cover-4 defense both S's need speed to play the run. At S, your speed is huge when playing the run because it's about angles, getting to the RB before he's through the hole, rather than at the hole. At the hole it's a 3-yard gain. Through the hole you're forced to make a tackle in open space. Those are the ones that have potential for big runs.
The tea leaves were there when Richt and Diaz talked about tackling being the most important thing at S, and how when you look around the country at all the big plays you see, it's usually because a S missed a tackle.
Diaz and Richt value tackling above all else at the S position, so in that respect this player fits the bill.
Hope it works out.
