At the end of the game, if the other team is one or two points ahead, a team goes to its best isolation player. Often, they will clear one side of the floor and let the clock run to 5 seconds. Having a good isolation player is crucial to being a good team. Here's who you want in isolation plays in general and, especially, at the end of games.
10. Lebron James
Surprised to see him so far down this list? If you saw him try to catch the Heat up with an untimely 3 point shot that hit off the very top of the backboard, or any other unsightly jump shots, you would understand. Isolation players do not need to be able to nail 3s, there is usually some other player on the team for this role (in Miami's case, Mike Miller.)
They do need to do 4 things well: get to the rim, get fouled, hit free throws once they are fouled and hit midrange jumps shots. Lebron scores an A+ on the first two, a B on hitting free throws and an unfortunate C - when it comes to hitting jump shots. This is not going to put you at the top of this list.
