Rookies aren't always not as good as the non-rookies. Senna kicked some good ass in GP2, and deserves a spot in F1 more than some people in F1 do today. I'll use Lewis as an example. He was F3 champ, GP2 champ and, in his first year, came 2nd in the WDC, ahead of his old-timer team mate, Alonso. And the next year, he won it. F1 teams have this mentality that an old timer is better than a rookie, and this is something that will be a setback for drivers trying to enter the sport. So i'm glad that these new teams will be entering F1, it will give drivers a chance to enter the sport and stop waiting.
