Probably because they harken back to the times that drivers actually had to know something about vehicle dynamics other than holding on to the steering wheel and mashing the gas.
That being said...
Believe this is the crux of the subject right now. Pocono was fairly interesting and need more proof, but followed each lap time from the start of the race until the end. Kenseth's lap times (fastest on new tires) dropped after four out of his six pit stops. He was almost a second faster at the end of the race than the beginning. He was barely bumping 170 average speed in the beginning and was just about 172 at the end (believe that was faster than he qualified at). At each pit stop changes were made...apparently some were better than others.
At Ricky's last pit stop, they made a Kenseth suggested change...Ricky picked up .3 tenths of a second on the last run.
RFR still has a major balance issue though...similar to Johnson did earlier in the year. Do not think RFR has the talent resources in the back room yet though.
