Moving from one rookie to another, and without a doubt one of the most disappointing first year displays came from Jadeveon Clowney. He failed to register a sack in his meagre four performances during an injury-plagued season. Of course, it's not entirely his fault. Injuries are mainly down to chance. However, in the games Clowney did play, he looked unconvincing, and while he'll be fit and raring to go alongside J.J. Watt and Vince Wilfork this season, he hasn't proven himself to be worthy of the top rookie rating dished out by EA last year (83). For now, he could be around a 79, but with a good 2015, that could spring back up depending on how he settles into the league given a regular run in the team.
