Arnie and I had an insightful, in-depth conversation with Chicago Bear Wide Receiver and Special Teams man - and Havre, MT native Marc Mariani.  We talked with Mariani about what it really takes to be an NFL player, the hard work, training and commitment.  Listen in on Sunday morning at 8AM on KGVO to hear what Marc thinks about his fellow Bears players, his Griz career and how defensive players on other teams try to "mess with his head" during games.  He makes a prediction for Sunday's big game too.  Tune in to "What Do You Know" this Sunday morning to find out what makes Marc tick!
