Johnny Football 2.0 on full display in Browns’ home opener

Off the field is not a question for the Cleveland Browns, who feel Manziel — making his third career start Sunday against Tennessee in replace of injured Josh McCown — accepted the guidance from the new offensive staff.

As colleague Pat McManamon pointed out, the Browns were ready to start the concussed McCown after one day of practice if he was cleared by a neurologist in time.

Another four quarters this week might not be enough, either, but there’s a real, unclouded quarterback ready to be evaluated off a full game plan after a week’s worth of starter’s reps.

The timing is good for the Browns, and it’s good for Manziel.

The last time Manziel took the FirstEnergy Stadium field in Week 15 of last season, friends and family came to watch, a white SUV dropped off Manziel in an alternate entrance to avoid awaiting media, merchandise businesses hung No.

This day would launch Manziel into a new quarterback stratosphere, as the theory went.

Manziel and the Browns can assess their marriage on their own terms.
