Horse Collar or Not?

That's the way I understood it as well. Another defender getting involved doesn't automatically mean that there's no HCT. If he's already being pulled down by the tackle, and B2 hits him on the way down, he's still be horsecollared. But if B1 holds him by the collar, and the B2 comes in and is the one who makes the tackle, no foul.
