Manziel admitted his mistake during a media session on Saturday and said he "misread the schedule."
"I personally don't think it had any decision on going into this week,'' he said. "I misread the schedule on Monday. I think we had to come in at 7:30 and I think it was the only day that we've had to come in at that time throughout camp and I was on time for what I thought was our normal 8:15 meeting time, so it was just a misinterpretation, a misreading of the schedule. I sat down with coach Pettine and I talked to him and we handled it and we've moved on.
"Obviously it's something [where] I just need to do a better job of reading the schedule the night before but it was an honest mistake and something I need to learn from and make sure it doesn't happen again."
Did the dog eat his schedule, too? Just kidding. I do stuff like that all the time. So does everyone else.
Manziel has hundreds of things he's trying to deal with and figure out; the schedule is just another burden for the rookie as he migrates from being the biggest fish in a fairly large pond to a pretty average-sized fish in the ocean.
The difference is that even though he's not the biggest fish, he is the most-watched fish. Even though it's a worthwhile story from the standpoint of being "news" it's also the height of silliness in terms of people melting down about Manziel's every waking moment.
As we've said all along, the only thing that really matters is whether Manziel can manage to beat out Brian Hoyer for the starting job in Cleveland.
It looks unlikely at this point -- Hoyer will start for the Browns on Monday against the Redskins -- but he's played well enough in limited action to ease everyone back off the freakout ledge that was his offseason. For the most part anyway.
