Yeah, I know all this stuff. I guess my point is that A) anybody playing QB can execute a shovel pass, and B) the read option is only effective if the QB is a legitimate threat to throw downfield. Tebow may be able to do a pitch-out or run the ball himself, but downfield he couldn’t hit a barn with a handful of rocks.
Some speculate that this is one reason Tebow has value to the Eagles, as a 2-point conversion specialist. However I doubt it as the Eagles generally don't dress their 3rd string QB. I think Tebow could make it just because Matt Barkley stinks so why not keep a guy like Tebow who can at least be a threat to plow through a defense personally? Nothing to lose, if 3rd string QB is starting games the season is over anyway.
