so, McCallum's third year is unguaranteed until the 12th of July 2015, at which point it's at 200k$, and becomes fully guaranteed if not waved by the 20th. so if no decision about his place on the team has been made by the 12th, the FO has given itself an eight-day window, before he becomes fully guaranteed? that's...quirky. wonder what the reasoning behind that was.
