Arnette wasn't as bad as people think. Played with a broken wrist. Physical DB that can cover just fine. Red Flags were for off the field stuff, attitude etc..Several had him as a 2nd round talent. They didn't have another pick until 80, didn't get an offer they liked, kept the pick. Took the guy they liked.
After the first 2 DBs you could throw them in a hat and pick one. People get way too caught up in draft guides. Its an inexact science, aside from the obvious top players the rest are graded all over the place. WR lists were all over the place.
Safeties targeted for 1st round went in the 2nd. Terrell went 16th. Look at the receivers that slipped down the board. Several 2nd rounders went later than expected.
Everyone has their opinion on when a player should be taken, which is fine. I can make a list a mile long of Top 10 picks that were awful, while players taken after excelled.
Until they line up and play, nobody knows. The most ridiculous exercise of this process is everyone wanting to grade drafts before any of these guys plays a snap.
