TCU defensive scheme is just coming to grips and accepting the split-formation concept they utilize.
rules we already covered, we plainly go over adding another receiver (3) to the read side.
In the worst case scenario, “all verticals”, the corner will zone turn to bail and split the difference of #1 and #2 receivers. The free safety will backpedal weave leverage of the vertical #3 receiver. This is the ‘jailbreak’ option versus this coverage, if three verticals aren’t run to the trips side, the pattern distribution can easily be accounted for in the rules.
So if #2 receiver or #3 receiver is not vertical, now we're back to the manageable 2 receiver threat. If #3 runs a shallow out (for example) the free safety is no longer threatened in the middle of the field, so he will settle and look to rob any route by #2. The corner will have the post by #1 all day, so the free safety is free to look of #1.
This was just an overview of the split-formation coverage of TCU out of their robber package. Feel free to check out the RUNCODHIT articles on their usual 2x2 coverage (Blue/ Cover 5) that we’ll see a lot of in their push for National prominence this season.
