I don't understand how July 2019 was too early, but December 2019 will be perfect. It seems to me the only thing different will be the 2019 season will be over. What else? I also don't think that adding difference makers in MLB is like shopping on line at Amazon. You can't just wait until the perfect time to buy, there isn't an unlimited supply of the item you want. I don't think Houston made a conscious decision to wait a year to buy Justin Verlander. I think when they did, they realized the opportunity to do so was rare and fleeting, and they better do what's necessary to complete the sale, because tomorrow there most likely won't be a Justin Verlander available for purchase. I think they would have gladly made that purchase a year earlier, but they couldn't.
