If number one, number 2, and 3 of Dickey, Marky, Morrow, Stroman and Hutch are slightly above average the Jays will make the playoffs.
I think what people are underestimating is the probability of this happening.
Say there is a 90% chance for each of Bautista, Reyes, Lawrie and EE to be healthy... there is only a 63% chance they will all be healthy.
Then say there is a 50% chance Lawrie will take a step forward. That means there is a 30% chance they will all be healthy and Lawrie will step forward, blah, blah, blah.,
After working it all out there is only a minute chance, 1 in a million probably that your scenario as written comes true.
The good news there are other scenarios that produce a pennant. For example Bautista, Reyes and Dickey play at peak MVP like level (with only other minor things going wrong).
Stroman and Hutch battle for rookie of the year. Morrow pitches 200 innings with Lawrie playing 160 games.
These projection systems take all this into account. Some of them I think simulate seasons thousands of times. I guesse those simulations give you a good idea of the odds. Haven't seen that type of data this year. But I guess the 2014 Jays make playoffs 5-10% of the time in those?
