It has been a great regular season. To be able to ask the question, "was this the best Blue Jay regular season in team history?", without gales of laughter ensuing is a rare treat. So, let's do it. With some statistics and some flights of fancy.
We have to first define our terms. What do we mean by "best regular season"? Teams go through arcs over a regular season, and the 2015 Blue Jay season was a pretty extreme example of that. If we are trying to measure the best Blue Jay club at a point in time, this one is (to my mind) pretty clearly the best.
