You use the press coverage when you can. Here is how teams play tOSU. They know tOSU sit back in coverage so they have quick hitters that become big hitters. Why? Because the DBs do nothing to impede their progress early in the route and break the timing of their routes. Most teams only have a few players capable of playing press coverage. You play it if you got them. If you don't then you go with option B. If you go with option B, be prepared to get nickle and dimed to death cause that is what happened to the tOSU pass defense all season. Also playing more zone would prevent long pass plays from happening, but even that wasn't the case. The Bucks got burned long as well. Don't even get me started on the screens which the Bucks failed to defend all year. These teams know Buckeye D line is good so the pass plays are designed to get the ball out of the QB's hands quickly. This happens often since routes aren't jammed and receivers run free. QB throws to a spot and receivers are there to make the grab. Happened all year long against the Buckeyes. We all saw it game after game.
I believe the Bucks have talented DBs in the fold. I question how well they have been coached and I have questioned it the whole second half of the season.
Another thing, if you are going to play zone, you have to be very solid at reading offensive alignments. The DBs were not good at making reads nor was any of the linebackers this season. While Shazier could make some phenomenal plays, he wasn't reading plays very well. Nor was he helping the lower classmen get into the correct defense. I'm not trying to call him out singularly but he was the most seasoned player out there in the backfield. Well him and CJ Barnett. They basically had no leaders on the defense after Bryant went out. The read issue is a coaching issue, but the leadership issue will require some of the new players to step in and take the helm. Show the tough love when needed as well as point out the keys and get players aligned correctly. All of these things have to happen if the defense is going to get back to the Ohio State defense we love to watch.
