Alright, appreciate the input.
I am still wondering if two different SAs can be fired simultaneously by the same player. For example, if a punter were in a situation that satisfies both conditions for firing 'Pinned Deep' and 'Three & Out,' which both increases the punt velocity, is it possible for the punter to fire both SAs to get bonus from both? This kind of thing should happen to many other position players as well. (GLBack + Grinder for HBs, Laces Out + Chip Shot + Streaky for Ks) They are the ones that take effects for the entire duration of the play, and I just happen to not have seen them firing simultaneously.
Or, how about the ones that take effects for a short amount of time? Say like, 'Spin Cyle' + 'Tunnel Vision'? or 'Juke and Spin'? There are dozens more combinations that can theoretically fire simultaneously, but I just never saw that happening. How about you guys?
