Holl is pretty serviceable if he can be carried by a competent partner. He's not afraid to take hits to make plays, and will block shots. He has his limitations, but so does pretty much every player. It's on the coach to find a way to get the most out of his players, and Keefe clearly drops the ball with Holl.
What can't happen is another night of Giordano-Holl playing like they did in game 1. They have been pretty good together most of the year, but Tampa did an incredible job exploiting their lack of speed and mobility and they were both frankly soft and made sloppy mistakes that can't happen in the playoffs. It's probably not a matchup you want to throw out there for Tampa to exploit, because they've proven that they easily can.
Also, maybe they didn't need to play the 39 year old in 78 games this year. I wonder why he looks so tired
