Dale Earnhardt Jr. - Communication with pit crew problems

Let me first state, I LOVE the Earnhardt's- was a fan of Dale sr. forever and like JR. just as much. The following is an observation of the situation the JR. is in
1) JR. does not communicate with the crew as to exactly what the car is doing. I have noticed in countless races that they start off fine but never are able to keep up with the changing track conditions
2)Pit stops are marginal at best....most times loosing valuable places that took him a complete run to obtain....in my opinion the complete pit crew should be changed with the goal of always completing stops in under 14 seconds
3)Crew chief should be replaced with someone who is more educated in the dymamics of the new cars and how to set them up. The current situation will just lead to more mediocre finishes.
If you notice there is a tremendous difference in the information exchanged between Jimmy Johnson and his crew and Jr. This has to change if he is ever to achieve the goal of champion.

I root so hard for him that I am just frustrated that even with the change in teams there now seems to be a drop off every week from the previous one. I think the edition of a qualified engineer to the team would do wonders to solve the problems that I see here.
I hope no-one considers this bashing because for what its worth I just think changes are needed if he is to compete for a championship this year. He is now in forth place but I see no improvement in making his cars better during a race...Thanks for listening and let me know what you think could be done....
