Not even close. Randy has a career that can be considered as, or even more, valuable than Pedro's because of more years of productivity, but at the apex of their careers Pedro's light shines brighter. From '97 to '03, Pedro put up an ERA+ of 218, Johson never had one season with an ERA+ over 200, his WHIP was 0.940, Johnson beat that in a season once, and his K/BB was over 6.00, again, Johson only beat that in one season once. This is a 7 year window where Johson's best seasons only eclipse two of those stats.
RJ just isn't in the conversation when it comes to trancendental greatness.
