Slowing the pace down only strengthens the Warriors defense, a defense which is already 100x better than the Cavs in a vacuum. And as you know, league-wide FG% decreases with every second that goes by on the shot clock - why decrease your chances even more against the best defense in the league; a defense which has multiple lineups that can switch on nearly every position?
Just look at how the Warriors can handle the Cavs when they slow the game down, look at the proximity of the primary and help defenders and how they have more time to think/adjust -
Look at how LeBron scored the majority of his points -
Early in the shot clock, before the Warriors defense had a chance to get set and work out what to do.
The only hope of winning is fighting fire with fire against this team. I said it last season when they were down 1-3 (as did Lue), and once they started attacking early, and got into their actions before the Warriors had time to get set and switch/adjust properly, what happened? They came back and won. Warriors went up 3-1 when the game was played at a 93 possessions per 48mins pace; the Cavaliers came back when the game increased to a 95 possessions per 48mins pace. This is just a example of what happened last season -
It was much of the same for the first half of the series, once they managed to find a ratio that favored shots earlier in the shot clock they managed to take a better control of the games.
