Present

Dirk Nowitzki's fade away and usual shots are almost 'unblockable',if he misses that's because he missed not because of some defense

LeBron James's dunk is most hardest to block because he has hang time,power and can do it at anytime.

Tony Parker's lay ups are hard to block

Past

Kareem's sky hoop was almost imposibble to block

Dr J's lay ups same because his hang time was just that good

Shaq's dunk............

Personla opinion

Dream Shake.

Sky Hook.

Awsome,next answerer pls!

Dwayne wades layups, He can change his shot in mid air. Remember the first game dallas and washington met last season when andray blatche blocked dirks fade away 2 times in 1 game. So it's definetly not dirks fadeaways.

Kareem and the skyhook. Most unguardable shot of all time.

For once, I agree wholeheartedly with ESPN lol.

Shaq and LeBron's dunks are hard to block.

Skyhook was pretty much impossible to block or defend really.

TonyParker's teardrop layup is also hard to defend.Its like the guys is having layup drills during a game.

Dirk's fade away shot is pretty hard to block.

Kareeem's Sky Hook

Hakeem's Dream shake

Dirk's one foot fadeaway

Cool answers,Iverson's lay up was tough to block too....................That's should get a honarble mention
