How about The Gambler with James Caan from '74? He's an inveterate gambler who gets in deep with the mob and ends up corrupting a young basketball player to pay his debts.

At the end Caan makes a shot from the top of the key and a hook shot. He really does!

You also get to see a pre-Alice Vic Taybeck and a less than rotund Paul Servino. You also get to see alot of long hair.

The last scene is quite a surprise.
