I sure do have my share WaT. I said that Rob Johnson would be a great quarterback and wasn't too concerned when the Bills got rid of Pat Williams. I also made a bet with cb97 that Aaron Murray would be drafted by the 3rd round (thus his signature which will probably stay up until Judgement Day )
Still, my record is better than all of the Bills GMs combined, and it pales in comparison to R.Rich, BADOL, most (not all) of the draftniks on this board, and a slew of other posters on this board. On THIS BOARD Wat!!! Maybin? An overweight, injured RT (Williams) over McKinnie? Whitner? Roscoe Parrish? Giving up the world for Watkins? Spiller? Two 4th round picks to move 8 spots in round 2 for Ragland? I left out a slew of disasters, and won't even get into the nutty, weird extensions and free agent signings.
But in any event you are right. Pros will miss on draft picks very often, let alone people like us. Still, it's almost as if it would be hard to draft as poorly as the Bills even if one was trying to do so. We will know in May of 2018 if things have changed.
