Far be it from me to question any college football coach...but, still, my eyes haven't lied to me all season. Are you referring to that infamous "bubble screen," where the QB shoots it out laterally to the far WR behind the scrimmage line? And then guys are supposed to block for that WR?
I think I have seen that play pay once all season...but it paid big. Crooms took the pass and split the two DBs before they knew he was gone...and he was gone after having just squeezed between them. Outran the secondary for six.
Other than that, I have seen that play get stuffed for either no gain or a loss enough times to last me a lifetime. Once, I think it was against MO, our receiver caught the pass and there was not a single UT blocker anywhere around him. He was surrounded by three defenders, who TFL'd him for 2 or 3 yds.
Again, I'm no coach and I trust our coaches implicitly...but, man, I just don't recall having seen that play work very well at all. And our coaches talk about consistency...that play seems to consistently be a yards-loser.
