Alright, I'll treat it as a called shot to knock down, but you can still act and then go on full dodge as an interrupt action. This is an opportunity to act first when you're outnumbered 5:1. If you want to hold back still, well, here goes.
8d6.hits(5) → [5,4,4,5,6,3,5,5] = (5) Crimson goes down to the ground at the feet of 4 gangers who now have the advantage of attacking a prone character (+3) in great numbers (+4).
14d6.hits(5) → [4,5,2,6,1,5,6,5,4,3,6,6,3,6] = (8)
14d6.hits(5) → [6,4,3,4,4,5,6,2,1,6,3,3,6,3] = (5)
14d6.hits(5) → [4,5,3,2,3,6,2,3,6,4,1,6,5,6] = (6)
14d6.hits(5) → [1,2,4,2,1,4,3,5,1,5,3,4,2,1] = (2)
Base damage is 2 Stun.
My guess is that Crimson will get stomped into unconsciousness.
