First off, Kyrie was available before Game 1, we didn't know he'd be lost in the 1st game.I forgot about Lakers Nets
warriors Cavs '18 more predictable than Warriors Cavs '15 it was Lebron James and Matthew Dellavadova against the West All Stars starting five
Second, out of the first 3 games the Cavs won two and had a shot to with the other. If they were up 3-0 the Warriors might have folded. But the Cavs didn't have the bodies to put that effort up past 3 games - Shrump was hurt, Delly was hospitalized, and Bron was wasted.
Difference between 2015 and 2018 is that the Warriors were still fresh in 2015 and vulnerable. In 2018 they were a known factor and their floor was really, really low. With KD-Steph-Klay-Iggy-Dray all playing in their 3rd Finals there was just zero chance that they were going to fold up or choke like the 2015 team might have.
Also, Love was so pathetically bad in the 2018 playoffs that the 2018 roster might as well have been as sorry as the 2015 one. He ONLY scored in series that were already decided.
