No, the third step I see is a foot. Momentum or not, both feet in bounds with control of the ball until he reaches for the finish. If you watched it 12 times and couldn't see three steps, you are biased. A BS call, but whatever. I am hoping all teams in the future challenge every pass so the majority get overturned until whatever interpretation is in the rule is removed and there is actually something factual and measurable by which a call can be made. The rule is a problem because it gives the ref a free pass to choose whatever outcome they want instead of relying on anything concrete. Rules are supposed to prevent that, not encourage it.
Anyways, can't believe the Ravens lost. Brady had a pretty sick game though
