On the play to the side opposite the pressbox, no question - clearly an avoidable late hit OB.
On the kickoff to the pressbox side, it just doesn't jump out as being a late hit, althouh the slo-mo replay shows contact at about the same time the BC's left foot comes down OB. The fact that he was being blocked and forced to the out-of-bounds area, and the closeness of the contact with the BC actually being OB, makes this one a no-call, IMHO.
