That is something we all felt.
And they fucked themselves by not doing this earlier. I think Bisciotti wanted to fire Cam the last 2 years and was talked out of it by Harbaugh.
I think he has hit his boiling point probably.
But it's really too late right now. They aren't going to know anything for sure off of a 3-5 game sample of games.
I said it before and I'll say it again...the team royally fucked themselves over by not firing Cam to see what they had in Joe. A lot of people have higher faith in Joe with a new OC than I do, but you just don't know and they won't know going into a year where they likely will have to franchise him.
