The Ohio State Buckeyes made some big changes before the Tulsa game in an effort to fix their struggling defense.

Kerry Coombs was replaced by Matt Barnes as the primary playcaller, and Coombs got moved upstairs to the press box.

Some new players got an extended run, including promising young standouts like Cameron Martinez, Tyleik Williams, JT Tuimoloau, and Jack Sawyer.

And while the run defense was light years better, there were still some troubling warning signs with pass defense, the utter lack of pass rush from most of the defensive line, and a linebacker unit that still seems like it has more questions than answers.

So are more big changes needed? Buckeye Scoop's Bill Greene joins host Tom Orr to discuss that and much more.
