The whole team seems to lack situational awareness, not just Sefo.
You saw it several times during the season, not even trying to get out of bounds to stop the clock, running sideways to try and make a "big play" instead of just falling forward for a first down, running a 7 yard route on 3rd and 8, the list goes on.
If the problem extends beyond one player it's on the coaches, not the player(s).
I'm not sure if the coaches view those things as "Football 301," and they're just trying to get everyone to master "Football 201" before they seriously start teaching/emphasizing it, or if they're unaware of how to teach those things and assume it's one of those things where players either have "it," or don't, and these players apparently don't.
I suppose the other alternative is that they're not looking at it systematically, and know/want to teach it, but they keep getting bogged down with "no godamit, for the 100th time, this is how you're supposed to line up for this play call." It's the same thing as the 201/301 thought, but with less of a big picture strategy driving it.
Long post short: I put this issue on the coaches, not Sefo.
