fatty, I could be way out there but I'll say this; Childs is the most athletic/impressive I've seen at DE (granted, in very limited looks) since DH at the same age. He reminds me of Howard's quickness and speed at that age, but Howard was also undersized until his JR and SR years and got manhandled at times by teams that ran right at him.
I don't know yet what the new sceme will do to protect him. For example, we would often eagle (which means you slide your defensive front over a gap to the strong or weak side of the offense) our front in Snyder's defensive system so that we brought our Sam LB onto the LOS on the TE so the DE on the strong side was covered up and protected a little bit. We'd then put a bigger player at the weakside DE with no help who could hopefully handle the run a little more on his own. I don't know if this version of the Tampa 2 will do that or not, I didn't see us playing our Sam on the LOS much saturday though.
