Block. Defender wasn't there
LGP is established and the defender moves backwards maintaining it...
Block LGP was not established
Defender is sliding to his right. No legal guarding position was established. It looks like a block.
Call the travel that occurred and get out of a block/charge call completely. Otherwise, the block call was correct. LGP wasn't established before he started his shooting motion. 2 shot foul.
I agree with Michael Jones.
Block. Slides under.
