I've been thinking about this for a while, and the video explains it perfectly. Sark doesn't gameplan because he doesn't think he has to. That's a lesson he learned from college football, and it's a big reason why I think a lot of college coaches fail in the NFL.
The reason: they simply cannot comprehend the talent parity in the NFL.
College football is so uneven in terms of talent because of a few reasons. First, players are recruited and ultimately get to choose where they play. This means teams like Alabama and Clemson have five-star recruits two deep at every position. Second, the best players usually leave every three years, so even if a star emerges at a lesser school, you'll still need recruits to replace him. Revert to Step 1, and the cycle continues. Third, the talent pool is just too diluted. There are 130 D-I programs, each with 70+ players. That's over 9,100 players, whereas the NFL has only 1,696 (32 teams with 53-man active rosters). And the NFL players play as long as they want/can.
So coaches at top-tier college programs simply gameplan as they please. They know they have more talent, and talent normally wins. These guys are so used to being able to inflict their will on the game that they don't even consider what the opponents might try. They run the same plays over and over because they know the opponents can't stop them (a trademark Sark move). They don't get how this doesn't work in the NFL.
Where do we see this with Sark?
He abuses the Hooper motion on so many plays. Usually, as the video says, he uses motion to diagnose the coverage, and normally, he motions Hooper in. I'm sure college coaches don't trust their defenses enough, but the NFL defenses can disguise coverage. The Eagles even said they know the fourth down playcall as soon as Hooper went into motion. They knew his play because his love affair with Hooper motion. Also, his insistence on toss sweeps shows his college ways. Very rarely did they work to Atlanta's advantage, but he insisted on them. He kept doing it because "Hot damn, they can't stop my awesome toss plays all night!" In the NFL, they can.
As the video says, he doesn't game plan. "Why should I? I have Julio. He can do what he wants." Sark seems to think his offense will just work against anyone. Why else do you line a FB out wide against a corner on the season's decisive play? Because, as college coaches think, the offense's talent will win out. Why make them respect that side of the field when my talent on the other side will win? Sark calls plays like a college coach, and it's so hard to watch.
Tl; dr: College coaches are tainted by the college game, and when they get to the NFL, they think they will be able to dominate with no planning. This doesn't happen.
