They do not need a winning streak. They just need enough wins to enter the play offs and do everything from there. They should learn from GSW last year, they have the most wins, streaks but failed in the championships.
Basically yes but for a gambler they don't like the idea of their desired team to be lose. It will wreck their p2p gambling system, normal bet and parlays that will made.

They are all important. Cleaveland always end up losing if there is an injured key player in their teams. That means cleaveland is not a one man team unlike oklahoma thunders team. I hope kyrie and love will be back sooner so that they will have a winning streak again
Unfortunately that is not the current view on the Cleveland Cavaliers although we can really see that all players there are distributing well. The record was 3-12 since the start of the season.
