Well to answer your first question. It is my opinion that the reason Jr. has had only one points race win is because of several different factors. It could because of how the cars are built at the shop. Could also be bad communications between driver and crew Chief. The funny thing is that some many people on Y!A think that just because Jr. is the most popular driver that automatically makes him the best driver ever. What I don't understand is why don't people rag on other drivers who had success early in their careers. For example Jeff Gordon went I think almost a season and half with out a win. Why, does nobody pick on him? What about Joey Logano aka Sliced Bread. He was supposed to be the next great thing, but he only has one win.
The only people that think that racing in the Nationwide series that think it is minor leagues are the haters and not just Jr. haters. Winning a championship in any type of racing is a big accomplishment. In other words it means that for that season that team was on its game. If a team can repeat it shows dominance. Take Jimmy Johnson for example Mr. 5 Time. The 48 team has won an impressive 5 championships in a row.
Minor leagues of NASCAR are the Whelen Modified series and the two KN series. Not Nationwide or Trucks.
As far as I can tell not one person considers Jr. running in the top 10 a better accomplishment then winning. Oh, wait the ones who do are the haters. Yes, when Jr. finishes good people do tend to talk about him but that also goes for any other driver.
I hope this clears up any confusion for you, and if it does not then maybe you should follow something a little less complicated, like competitive tic tac toe, or even coloring inside the lines.
Now we have are first nominee.
