Champions speak thru their actions.  The more the Bears talk about defense instead of delivering it, the longer the season will be.  Despite the risks to injury, the team needs to start hitting in practice, specifically tackling.  Being healthy and not being able to perform because of poor coaching, schemes and soft play and execution is worse than not fielding your alleged best team because of injuries.  Man up, cut the crap and hit somebody.  Early, often and hard.
