The eleventy billion posts about how Tate should have been in for the last drive and how RR blew it are blowing my mind! Did you people watch the game?
If anything, Denard should have seen action much earlier. Tate was having trouble moving the ball, had communication issues, and was turning the ball over--all expected from a freshman--nonetheless Denard should have seen the field earlier.
The main argument that I might listen too about getting Tate in there for the final drive is the fact that having Denard run the ball would not be clock efficient enough to get into field goal range. That is it.
