...clipped because I didn't care...
I don't think anyone would say they're *just* a lucky team, but surely you'd agree that they've defied the odds with some very good short variance lately. Of course good teams and ones with good psychology are in positions to cash in on that luck more than weaker ones, and that holds in any sport. But they have won several games where they've been, at some point, at least 10-1 underdogs just based on the score and clock. Whether you want to call that 'luck' is just a quibble of nomenclature. I'm a pretty big gambler so that's the term I go with
but your mileage may vary.
