DC, lots of very interesting stuff in your PDF put up recently. Please excuse me for not searching this subject thoroughly, but I'm down to a modem cx this weekend, so someone has likely asked you this one in years past (assuming it's not new info).
You say you gave it a good try, but couldn't get the buck sweep series to work with kids. What went wrong? Was the problem with the sweep or with the buck or trap? Was the faking not good enough? Did the defense penetrate and hit the QB while his back was turned?
I may never coach wing T or your flavor of it, but if I ever did, the buck sweep-waggle series would've looked particularly attractive to me, threatening a quick hit and not requiring a reverse pivot by the QB to open. Of course I'm sure it was attractive to you too, although maybe for different reasons, so I'm curious about its consistent failure in your hands. It's intriguing that Ted Seay doesn't have a buck sweep series in his wing T for youth either, although he does have a belly sweep.
