Della is a very good player and these minutes have shown that. He is a traditional PG (which I like watching) who plays great defense and is pass first/penetrate often. You just don't see many like him any longer as most settle for outside jumpers and hardly ever play defense. I miss watching the Stocktons and Paytons who stood tough and right in the face of the opposing PG. Not to say he is at their level of course but it's just nice to watch a PG play stuff defense and pass first options.
Cavs have played like this the entire series to be honest. It's just that being at home changes things of course. The Warriors better pull head from ass in a very quick way or they will be going home down 3-1.
