Reading between the lines from the quotes from all of our coaches heading into the season...
they seem to be confident about QB, RB, WR, LB, and secondary.
they seem unsure about both the DL and OL. Snyder has always found a way to move the ball whether he had a really good OL or not. He's a master at squeezing a gallon of lemonade out of one lemon, offensively. But defensive line is another matter. It's not that they don't display any confidence about the DL it's that their words are very measured when discussing it.
