No one should be getting excited about a roster of old and/or injury-prone players that will underperform against the physicality of the playoffs, especially Golden State.
The Cavs did not get better, IMO. In the NBA, four quarters do not equal a dollar, not even sure they do 75 cents. This year will finally be the year I believe that armchair RealGM/Reddit types finally realize just how valuable Irving's dynamic scoring skillset is in the postseason, while the analyticphile Jae Crowder types fail to move the needle. There are literally still people who think a player like Irving who have proven capable of putting up ~30 points on damn near 50/40/90 efficiency in a playoff series against a spectacular defensive team like Golden State is not even a top 20 player in the league and whose contributions can be more than made up by Isaiah Thomas and Crowder.
