Most predictable offense ever!

I know CJ is all that but unless we try to mix things up a little but most teams are just going to load up the box and shut him down unless we open up the offense some. I know our WRs aren't the greatest and VY isn't amazing either but I think we can make plays if we pass on any down other than 3rd. When we need a drive to run some clock when we had the lead we ran to very obvious running plays with CJ and then tried a play action pass that ended up stopping the clock. Does Heimerdinger suck or is Fisher not letting him call his own plays?
