Jaquan isn't really a prototypical free safety. He could work hard and do it, but so far he's been used much closer to the line of scrimmage, either as an in-box thumper or a nickel. Carter and Gibson have also been hitters rather than center-fielders in high school. Heard somebody talking about Finley moving to linebacker like it was a confirmed fact. Not sure about that, but he's also definitely a strong safety rather than free.
Doesn't leave us with many legit options for the other spot, which might mean Jaquan will end up there out of necessity. That's why Collier and Edwards are so interesting to me. Both could definitely play free (although hopefully we have better options for next season).
