Several people to respond to so I'll just take yours as one who is pointing out that they had same equipment etc. Dominance in almost every sport has been rife with potential controversy, whether it's assembling the largest group of stars in a team beyond anyone's grasp (Patriots, Bulls, Real, Man City, etc), doping and steroids (which was very common in the 90s and before...hi track and field, cycling, boxing etc), nutritional tricks, or tech gimmicks (i.e. swimsuits to improve wake, custom developed golf clubs, etc). Formula 1 is no strange to that over the decades of course. To say any of the other sports were simply down to the athletes alone having the same tools, whether material or support personnel wise, is terribly naive.
