Thanks for the clarity and for such a thorough explanation, although I’ve got to admit that (right or wrong) I still have doubts as to their method in terms of win probability. I’d be interested in hearing the opinions of some other degenerate gamblers besides myself.The odds are at -150 to play and +120 to sit. The “true odds” would meet in the middle at -135 to play and + 135 to sit. The reason they do not align is so Vegas can make a profit.
At -135, the percentage odds are actually at 57.5% (a little less than 60%) that Gronkowski will play. Even if you used the -150 number, that would be exactly 60%. So, somewhere between 57.5 and 60% in Vegas.
Just put in -150 odds for the probability in percentage form, likelihood of it happening.

I say that is pessimistic because, though it is slightly more likely than not he is cleared, that number is not much better than a coin flip and probably much lower than the great majority of people would assume. Chao’s article cited that 90% of players return from a concussion within two weeks, and there are probably players who choose on the side of caution if their team is out of contention. I would think Gronkowski’s chances of playing would be much greater than that particular prop bet line from a sports book. So, in context I think those odds are pessimistic, though there is probably a better way to describe it, like “less optimistic.”
I mean, one can argue that it’s right there in black and white, but even when you plug -195 into the calculator it still only raises the win probability to 66.6%. It just seems a little off to me. I could be wrong.
