A couple follow ups to get deeper into the actual calls
for 4th quarter, Georgia 16-13, 1st & 10, Georgia 14, 29 seconds left
the play call is double screen Y delay as seen below. The first and likely only read is the TE after the double fakes. To me this highlights how Sark can get lost on 'cool' plays that make you look like a genius when they hit, but are foolish when considering the current context you're in. This is a long developing play as you mentioned, and it only has one real option, though of course if the OL could've somehow held up for 5 seconds I assume Quinn would've looked at Moore in the endzone. How likely is that against a Georgia team that has shown it will beat your OL relatively easy and frankly seems to know what is coming a lot of the time.
Final play
this is a play called Mesh Traffic, some examples linked to below. To answer your question, yes this is going to the RB all day. Which again, ignores the context of 8 quarters of play against a team like Georgia that is simply not going to get beat in the open field very often. If you're gonna run that play, it needs to be to Blue over Wisner, since his best skill is speed in the open field. But either way that play is another example of Sark getting too cute instead of running concepts with multiple reads. Perhaps he doesn't trust Quinn to go through multiple reads? Doesn't trust the OL to block long enough for Quinn to make it to multiple reads?
