3Randy Gregory

This is the name that is often mentioned by all Cowboys fans. Gregory was considered to be a top-10 talent, but his troubles with illegal substances prior and after the draft possibly ruined his career. God gave this guy incredible foundation to build a great career and if he could stay clean and train as hard as never before we are sure that he might have double-digit sack years in the future. It is clear that talent that Randy, or any other player, has is not enough to be successful, you need to train and perfect all those moves. Gregory has the potential to become pass rusher #1 in the league, but he can also fail and lose his job.
