Coach touching Player

[bgtg19]

I think MTD's situation is straight-forward. You have to T that coach who comes out on the floor.

Ref Daddy's situation isn't as clear. My initial reaction is similar to rainmaker's: if that coach stays out of bounds and helps up his player who falls right along the sideline in front of him, no reason to get involved in that.

But I've started thinking: what if a coach stays completely out of bounds, but helps up a tripped up player just in time for that player to catch a pass? Does that make the "help" different?
