Seriously though, Pop declared the rook not ready and elected instead to go with
Jacque Vaughn instead during Games 1-4. It was not until Game 5, that he decided to dust off Hill. Even though it was an elimination game, Hill appeared about as ready as anyone and performed well. In fact, he performed well enough for many of us to question why he wasn't getting more time during series.
Aside from all of that, JV was virtually ineffective during that series. Pop probably played that decision a bit too conservatively.
