This seems to be the running excuse for Whitt, "this guy or that guy is inexperienced", but these guys were probably the best players on their college team, unless of course they were a WR.
With all the draft resources thrown at the secondary I expect a lot more. I also expect even UDFA that has made the 53 not to make stupid mistakes whether its hitting a guy out of bounds, missing a tackle or crashing into your own teammate (something we have seen a few times this year).
I do agree with you, if you cut the head (MM) off the snake, do you loose the tail (Pettine). I would hope that the new Head Coach of the Packers will recognize that Pettine knows what he is doing and retain him....but ....*COUGH COUGH*....Fire Whitt. Hey....was I wrong about Janis?
