I really enjoyed the Glaizer clinic this weekend in New Jersey. Coach Rich Erdelyi put on a great clinic on new ideas with the Wing-T with mulitiple formations, Belly Sweep, and Jet Sweep.
I have not used the Belly Slide concept, but on the way home I was thinking of some new ideas.
The Truck play off of Belly Slide action and a double motion concept of the Belly Slide where the HB would go in slide motion, stop and set in the B Gap and then the opposite HB would go in 3 step motion behind. I have not worked out the timing but I do think it has some misdirection potential in both directions.
