Watched the replay, and I say I don't think he did.
First, he was engaged with Wagner, Wagner gets away, and IF Jarwin pushes him with any force, it was right two Dak. If anything, Jarwin helped him.
But I don't think Jarwin had any force in that motion because Wagner was able to pause before he launched himself at Dak's legs.
I'm not the type of guy to say that just because Jarwin is a Cowboy, but Wagner was not pushed over by Jarwin and still had a shot at getting Dak. Too bad Dak is a "Grown *** man".
LOL
