What It Means:

Perry Riley was expected to occupy one of the starting spots, but he was held out of spring practices because of a lingering foot injury. That opened the door for Compton and Foster to cement themselves in starting roles. Set to count $5.05 million against the cap in the final year of his deal, Riley could end up a cap cut if he is not able to claim a starting job.

In very limited time in 2015, Foster picked up 37 total tackles. When he gets playing time, he's a high volume tackle-racker, and Washington needs a physical presence inside. Washington ranked 17th in Adjusted Defensive Net Expected Points (NEP) per play in 2015.
