Teams have learned in today's super competitive world of NA$CAR, you can't have any throw-away tracks. This is why teams have zoned in on road courses. Not only stepping up the car program but sending drivers to Bob Bondorant's school, hiring coaches, etc.
It looks to me like if Robby intends to stay in NA$CAR, & really wants to be a better than 30th place team. Then it's time to put a full court press on the short tracks, Martinsville, in particular. I don't know how much info the Toyota teams share, but the car needs to be better. If you look at Robby's M'ville stats, (beyond ugly) it can't all be the car. We all know that Robby's background is not short track racing. There are plenty of accomplished drivers available who do have this background, & have had success on these tracks. Ricky Rudd, Sterling Martin, Rickey Craven. Hire a coach, take some time, & work on this. Today, tools are available that weren't previously. There are some very good simulators, so you don't have to drag a car to a track to test. With four short track races a season, even if Robby can improve to mid pack. The results should show in the points.
As a dedicated fan, last week hurt to watch. As a team, to have experienced this had to have hurt more. What they have been doing hasn't worked. It seems to me, that it's time to try something else.
