What has happened to ASU receiver D.J. Foster's production this season?

Arizona State receiver D.J. Foster was one of the biggest playmakers on his team; what has happened to his production this season?

According to AP Sports, Foster had at least 81 yards rushing/receiving in each game he played in 2014. Yet this season, per Greenspan's tweet, he's accomplished such just twice this season. In a recent loss to Utah, Foster was held to 11 receiving yards and -5 rushing yards. 

During ASU's win vs. New Mexico, Foster had just 16 receiving yards and 8 rushing yards. In 2014 vs. New Mexico, Foster recorded 54 receiving yards and 216 rushing yards.

"Yeah, I am (healthy)," said Foster, via AZ Central. "I mean, a lot of football played and I think we're all banged up and stuff. The bye week comes at a perfect time, trying to reload, but I'm healthy."
