If he can regain his peak form (which I doubt due to health reasons) I think he can 100% win. I think he is fully capable of delivering programs like Dennis put out there, and with his reputation and being on home ice he would outscore Dennis by a sizable margin. If Patrick is totally clean he should absolutely win, but Patrick is not a skater who is usually clean. The other top guys from Japan and Europe also struggle to deliver clean programs. Plushy is the only skater who has shown the ability to deal with Olympic pressure.
Plushy did not really "perform", he did some steps and one spin. Quite simple movements. Even his skating speed is not fast, so I think he is quite careful with the recovery pace (finger crossed).
