I honestly think this is where having THREE DAYS OFF between Games 2 and 3 hurts us.
Even if (big if) we hypothetically go up 2-0 in the series, that's three and a half days of more rest for Lebron and the Cavaliers, who now go home feeling energized again to try and take care of business (protect THEIR home court).
Our guys will get rest too, but if we go up 2-0, it will be primarily because we have momentum and have a formula that's working. Something CLE probably can't solve if there's a game every other day (not much time to practice executing it on the court as well).
However, they can make adjustments and such in that time, maybe even on the defensive end.
