DROY is a stats-driven award. Ndomakung Suh is the only DT to win the award since 1994, and only a handful of DTs had won it previously. Suh had 10 sacks in 2010, which is a significant total for any DT, never mind a rookie.
Are we talking about Easley netting 10 sacks in 2014? It's unlikely in a defense in which he is likely to rotate with WIlfork, Kelly, Silega, Armstead, Jones and Ninkovich. More likely, the DROY goes to Khalil Mack, CJ Mosley, or some LB who starts from day 1 and amasses 100 tackles.
