There is no debate regarding WHETHER luck played a role, because the laws of the universe dictate that it had to, one way or the other. The question is only, how much of the no hitter can be attributed to skill and how much to luck and other factors outside the control of the pitcher (fielding, skill of the batters, etc…). Even the best pitchers in the league expect some balls in play to find holes. No matter how good their stuff is or how crappy the batter hits the ball, some balls are going to eventually fall. For a particular game, sometimes a pitcher gets more of his share of hits than he deserves and sometimes every ball finds a defender. I think every baseball fan knows this. We see it every game. The league average BABIP is something like .300? (depends on if you are including HRs or not). The lowest qualifying BABIP last year was .257 (Wolf must have really been unhittable last year). Let's pretend that Jackson was just unbelievably "on" and had a true average expected BABIP for that game of .200. Roughly, the odds of having none of those 20 BIPs fall for a hit would be .8^20 = 1.1%. Even with Jackson pitching out of his mind, we'd expect about 4 hits. Even if we assume that Jakson pitched the best game of any starter in the league this year, he still needed a little help from lady luck. There is nothing controversial or complicated about it.
