So, Dunbar can play all the games in the pre season, but, I would hope the Rams get other guys, whether that is Witherspoon or Armstrong a good number of reps with the starters.
If it was roids or HGH (I agree that is probably the case....although there are alot of variables with roids) the risk is still worth the reward. If had been busted once already and continues using, and in that time frame went from being a minimum salary guy to a guy who is making $1.3 a year or whatever, paying out $300,000 is certainly a risk worth taking. If he returns and can maintain, or close to maintain, his level of play he has the chance to land a bigger deal after this one.
