Are we trying to pretend the team will tackle poorly during the season if they are not allowed to practice tackling our own QB's? Okay...derp derp....'cause there's just nobody else on this roster to hit is there? Oh, or are we saying our QB's won't be used to getting hit in the season if they aren't hit in practice. Yes, because they've only been playing football their whole lives. They've never been hit before.
And we only led the nation in fumbles for 3 yrs. Miss tackles, get off sides etc..... Unsure if I would use this argument for NU the past few years. We have sorely been lacking in fundamentals, technique and basic football skills.
You play how you practice. IIRC, last year we complained about the D just "wrapping up" and not taking people to the ground. Not advocating our guys getting hurt at all, but Jason Peter said that the beat the hell out of each other in practice and games were easy.
