Calvin Johnson: Is he getting enough attention from his QB?

I know that this post calls the previous post about the offensive line into question, but I still think Matt Stafford and Calvin Johnson aren't connecting as much as they should be. I know with a bad O-line it's hard for deep routes to develop and even harder for the quarterback to deliver the ball down field, but on occasions when Stafford has ample time in the backfield I don't think he is looking for Calvin Johnson enough. Yes he is the only threat the Lions have and is therefore often double covered, but being a man of his abilities I know there are occasions where he is either open or at least capable of coming down with the ball. In order for this team to gel offensively and to start putting points on the scoreboard our two biggest offensive guns need to be hooking up more often then they are right now. I'm not talking about short slant routes either, we need Johnson to be down field and have a ball heading his way. Who cares if we throw a few interceptions, we have won one game in a season and a half, lets at least see what potential there is for future seasons.
