Cleveland Cavaliers star Kevin Love just poured his heart out about his bizarre inbound play on Monday night ... admitting he knows he "f***ed up" and apologizing for his outburst.
32-year-old Love went viral for swatting away an inbound pass late in the 3rd quarter against the Toronto Raptors ... easily turning the ball over to the Raptors for a wide-open 3-pointer.
It appeared as if Love -- who's posting career-low numbers this season for the 21-40 Cavs -- had become fed up with the losing and just snapped.
