Yep, especially if he's putting up his regular season averages. It will just mean he was still healthy enough to get to the WCF, and him not making it will mean all his finals appearances were due to playing against weak opponents.
Now if he makes it to the finals as loses, at least there will be legit justification for it as he and his team will be worn down. That's why no one bats an eye at GSW 2016 loss. They had nothing left in the tank by the time they got to the finals. Just enough to win 3, and then they were depleted. The proof is that it was 3 straight, rather than one team winning 1 and the other team winning 2.
