In Brian McTaggart's sunshine-and-rainbows article on J.A. Happ, we learn how essential Happ was to the Roy deal:
"We determined that in order to make a sensible deal, we had to get somebody that was both a now and future piece, somebody that could come in and contribute immediately, but also had the ability to be a part of the program going forward. Aside from the physical ability that J.A. brought to the table, the fact he met those two criteria made him all the more key to making the deal happen."
