I don't think any of the current OSU QBs have anything to do with Kelly, he was headed to the NFL earlier this week. In fact I think all the QBs were pretty much in place before Obrien came in last month. Howard may work well with Kelly's style, but it may be more of a happy accident.
I don’t see anyone is claiming Kelly had anything to do with any of the current OSU QBs. I think what you see is a direction emerging that Day wants to do offensively.
