It's a coaches call! Some do some don't. The line of reasoning for many coaches is the time left on the clock, if there is 1.4 seconds on the clock what will kill you is the long in bounds pass, which even with a guy in your face you can still chuck it deep, thus drop the extra guy, create the jump ball at the other end, get the scrum going and the game is over, (typically what happens )with 3-4 seconds the plan changes because the offense can catch the ball dribble make a quick move and still get a shot. A pass to even a few feet in front of half court can kill you, even with a guy in your face you know well enough to chuck it deep and at that point you have 4 on 4 and not 4 on 5... The odds are thennot in your favor, you play the percentages. IMO, it was 100% the right call. you allow the 15 foot in bounds pass and give a 60 footer to win the game.
Even if Keita was guarding, I could throw the ball 60-70 feet and hope for the best because that is pretty much what it amounts to
