I was taught to take force plays at the plate from that spot. You can see the catch, transfer, and touch of the plate from there. Then it’s a matter of a read step to look up the line for RLV. There was lot going on fast here, plus he had to delay looking up the line because of the late touch of home by F2. As for getting help from U3 of RFU, someone else may know the 6 man mechanic a lot better than I.
