Quick Question for Rider Fans

Some of you can answer me this:

Greg Marshall was the Riders' defensive line coach from 1995 to 1996, and defensive coordinator from 1996 to 1999.

What was Richie Hall doing during those years, who recalls? Was he playing under Marshall, or was he DB coach under Marshall, or a bit of both ? I forget when he retired from playing. . .

I think he was DB coach

In 1994, Hall was hired by the Roughriders to coach their defensive backfield and worked his way up to defensive coordinator by 2000. He gained a reputation as one of the top minds for defensive schemes in the CFL and served as Saskatchewan's defensive coordinator for eight years including the 95th Grey Cup victory for Saskatchewan in 2007
