GREEN BAY, Wis. -- For now, you'll have to take Kenny Clark's word for it when it comes to the Green Bay Packers' new defense and the man running it.
Or Xavier McKinney's.
Or Colby Wooden's.
Or Eric Stokes'.
Or anyone who's been involved in the transition from fired defensive coordinator Joe Barry to new hire Jeff Hafley.
At this point, in the middle of the offseason program, that's all anyone can go on.
OTA practices, of which two have been open for media viewing, won't show it; there have been few full-speed team periods.
