The effort is there IMO, the problem is that their basketball IQ. Lebron will be effective someway, somehow consistently because he rarely makes dumb plays. Sometimes it just seems like Wade and Bosh are just clueless as to how they want to attack.
Bosh did some work under the basket with put-backs, keeping the ball alive, and/or outright just grabbing boards. He's not as effective if hes constantly taking jumpers that can't make consistently.
Wade, it just seems had no faith in perimeter shooting. Once he started taking and making some of those....it just opened up everything else for him.
Effort is there.....basketball IQ, not so much.
It all boils down to coaching.....which in turn is on Spo. Riley will never fire him though. Thats his protege, and the guy has been with the club and paid his dues for many years.
