Ohio's approach to stopping the run has always been for the defensive linemen to tie up the offensive line, allowing the linebackers to flow to the play, and it is the linebackers who make the vast majority of the tackles. If the defensive line is ineffective then the linebackers get blocked and can't make the tackle. If the linebackers aren't getting their job done, they also don't get the tackle. Thus multiple problems can lead to similar symptoms.
One of the disadvantages of the cover 4 scheme seems to be that if the linebackers don't make the tackle, the cornerbacks and safeties are not in position to make tackles in the 10 to 15 yard range, so once the running back gets by the linebackers the 10 yard run becomes 50 yards. With the cover 4 there are definitely more runs for no gain, or even losses, but also more big runs. I'm undecided if the trade-off is worth it.
At this point I tend to lean towards going back to the cover 2 most of the time, and using the cover 4 intermixed. The cover 2 gave up lots of 4-5 yard gains, but few super explosive runs.
