I can tell you were the red was 12 yards at least to the left of CVA couple responses:
- the ref's positioning: I dont know who even called it or where he was. I would agree that you should be in a good "position" to make a call like that but the call ended up being exactly right. The rule is really bad. Not the call.
- the subjective nature of when a slide begins. I get that its subjective. The rule definitely needs further clarification, I agree. However, if you freeze frame it and go frame by frame it, it is pretty clear he stopped his running motion to position his body into a sliding motion about 1 yard short. Then he is in a full slide at right about the marker. If you go frame by frame, you wont disagree that he's in a full slide right at the marker (and its 50/50 then if he is past the line to gain). But go back 1 frame and he is beginning his slide 1 yard short.
The rule sucks. It needs changed. But he began his slide too early. All this said, the ref shouldn't have called that given the spirit of the rule. Wake wasnt close to making a stop. No one would have argued if he gave him the 1st.
Not in position to determine that call accurately
