It's so funny to see other people's perspectives...
"Rg3 passing to his plethera of receivers"
you mean our plethora of nothing special receivers that every skins fan wants replaced as soon as possible?
(outside of garcon, as long as he's healthy)
"Jim Haslett is an excellent defensive coordinator who will show some unorthodox coverages and zone blitzes"
Why doesn't that work? Is it just too easy for the QB to figure out and get around in this scheme?
If the defense spends a player entirely on Griffin every play Morris is going to gash them. How many times have we seen a LB zero in on Griffin only to discover he doesn't actually have the ball.
The spy only really works on mobile QBs to keep them from killing the defense by leaving the pocket on busted pass plays. While Griffin running with the ball is incorporated into our scheme, we don't rely on him to scramble for tons of yards, and he prefers not to actually do that. A spy would be a waste against us.
