That is because Massa makes the Ferrari look worse than it is or maybe Alonso makes it look better than it is.
Of course, a lot of that might have to do with the Renault engine.
This may be Johnny Herbert all over again. IIRC Herbert was in line for a seat at Williams before his crash. If he wouldn't have been severly injured, then he might have been in the most dominant car of the 90s and possibly a multiple F1 champion.
I have a question for the F1 fans. Do you people prefer no rules in restrictions on engines or the aerodynamics? For me, I would perfer an unrestricted engine formula to the multi-millions spent on aero devolopment.
