"Senior safety Max Redfield, sophomore linebacker Te'von Coney, sophomore running back Dexter Williams, redshirt freshman cornerback Ashton White and freshman receiver Kevin Stepherson were all arrested on a misdemeanor charge of possession of marijuana in Fulton County, about 35 miles south of South Bend. Redfield, Stepherson and Williams were also booked on an additional charge of possession of a handgun without a license."
After this I believe he tested positive for weed during Jr season and then tested positive for weed a second time prior to Sr season.
Here's what he did on the field season by season..
FRESHMAN SEASON (2015) ***he was behind Folston, CJ, and Adams this season, so it's surprising he got any touches***

•Ranked fourth on the team in rushes, tied for fourth in rushing TDs and sixth in rushing yards
SOPHOMORE SEASON (2016) ***with Folston and CJ both gone, he shoulda got mad PT this season but he spent the whole year in Kelly's doghouse (aka sheshed) but he got enough touches in games that we knew exactly what he was capable of going into 2017***

JUNIOR SEASON (2017) ***didn't get anywhere near the PT he should have early in the season and then late in the season he was injured [subtitled: first weed suspension]***
