We average fans can only see the mocks and watch the games, and I doubt many of us have watched enough games to base our feelings on players on anything but mocks and predraft ratings. The reason we hear the words “coaches know more than us...” is that the coach’s have scouts working for them, who’s job has them finding out details that the rest of us will never know. Maybe a player is perfect for everything they want, and has a love for football and clicks with the coaches, and he’s the number 5 rated guy on most draft boards, but 1-4 like to party a little more and like to borrow money from friends and never pay it back, etc. maybe just maybe the coaches won’t draft any of those guys and want to draft number 5 before someone else. And then we fans see it as a reach, but the coaches see it as a steal.
