Pro scouts do not spend a ton of time on juniors because they do not know which are coming out early (except the the very best). So grades a year out are useless, moreso from the media experts. It takes an NFL team all season and the beginning of the offseason to finish scouting the seniors and juniors who declare. So your claim that someone who climbs a draft board be a one year wonder is kind of silly.
To claim that there were 3 dozen better is ludicrous and based on poor information if you judge by the NFL.com grades. Not even the draft experts here would make that claim.
You say Ted blew this pick. Alright, we'll keep track of those 3 dozen others and see who has a better career.
