You're not alone PGL, I underestimated him prior to the draft, mainly because there were alot of Safeties this year and I admittedly only looked at about 6 of them. When we picked him I went "oh, him? Isn't that kind of a reach though?" I truthfully didn't care for the pick, but he has looked good and his highlights online look like one badass Safety. I guess he's grown on me and it does look like he has coverage skills.
Hopefully we all WAY WAYYY underrated him and he becomes the best safety out of that draft class. That's my hope, anyways!
