Is the push by B1 legal?

CANADIAN RULING:

Legal.

[Warrenkicker]

9-2-3 A defensive player shall not:
b. Use his hands to add momentum to the charge of a teammate who is on the line of scrimmage.
Illegal use of hands or arms (Arts. 1a, 2, 3a, b, d) (S42)

So it sounds like it might not have been legal. It all depends on how B1 contacted B2.
