Having JT in provided the spark because of his ability to make the correct zone read option. How many times did he fake out the PSU defense and even the cameramen?
JT's running style is much more fluid and quick than Cardale's and we already know he can pass the ball well also - he just wasn't called upon very much to do so.
One of the things that raised so many eyebrows and dropped so many jaws last season was Cardale's tough running - even to the point of trucking a nose guard and many linebackers. I have not seen the same willingness to run tough from Cardale this year, except in rare circumstances. He seems to need a Devon Smith-type player to run under his bombs, which the Buckeyes don't really have yet this year.
Keeping Cardale in as starting QB makes it easier for teams to defend against the run because he is not recognized as quite as much of a threat. So far, he has had frequent misses and for whatever reason, disconnects on where the receivers are supposed to be or where he is supposed to be throwing. They're just not in sync and it has resulted in a lot of killed drives all season. Sadly, he hasn't helped himself with the NFL scouts this season.
On Saturday night, PSU kept Zeke in check for quite a while, until the running threat of TJ gashed them a few times, and then some passing options came open. It was much harder for PSU to know what was coming next and is much closer to what Meyer always wants to do with his teams.
Perhaps the injuries and suspensions and everything else that happened to our receivers really did make a huge difference to how the offense was set up, but going forward, I think JT needs to be the starter.
