ruby: you need to work on DI'ing the upthrow much more.
First game, his first grab: he had time to Nair, FF, L-cancel, grab, pause for a bit, THEN upthrow, and you STILL missed the DI :/
same thing happened second game except he fair'd. (and didnt rest this time for some reason)
Second game, you whiffed a grab right in front of him and also didnt JC it so u had mega lag, and once again, you somehow miss the DI despte that being what he was obviously going to do. Luckily he didnt rest you for some reason, or go for the upuair->tech trap->rest. I get the feeling he doesnt play puff regularly.
he shouldnt be getting potential rests like aerial->grab or when you blatantly whiff a move. You should be DI'ing these 100% of the time.
He doesnt even do any tricky grab setups like wavedashback oos->grab. so to see you missing DI on the most basic setups is like....meh
Upthrow Upair is bread and butter and you should get it down really well. You missed far to many due to slow reaction off the throw. Keep in mind jiggs is a lightwieght so you can move almost immediately.
at 2:15 you grabbed him near the ledge at 52% and fthrew....upthrow upait would have killed, you never gain anything throwing jiggs offstage.
when you fullhop nair and whiff, a lot of the time its better to uptilt than shine cuz it has more range and combo ability.
hope this helps.
