But you know that as n increases--as in, as more QB's fit the mold of doing a lot better with T.O. and Randy--the probability of them not being the cause goes down and down.
The strength of the argument for T.O. and Randy isn't that any particular quarterback has declined/gotten better. It's that nobody has gone against the grain--nobody has lost T.O. and done better, nobody has gained Randy and done worse. |
And you did realize the Montana case is weakening your argument, not strengthening it, since the change is minimal and you don't really have another side to compare it with. So you probably shouldn't have used it at first place.
