Sort of. I feel four ways.
First, I look at the immediate future and see that this C's team is capable of beating the Magic. Thus, to lose to them would be a disappointment.
Second, I look at Cleveland next round and see that there's really no way we're beating them four games without a healthy KG. Thus, to lose game 7 might not be a horrible disappointment.
Which brings me to my third feeling, which is that I'm curious to see if KG does come back if we advance that far. If it turns out that he might've been able to come back, I would be very disappointed with a Game 7 loss tomorrow.
Of course this all comes back to my fourth feeling: I'm disappointed the C's lost KG, but I'm happy with how they've been resilient without him.
