(Referring to the TD pass to Olave.)
This is a clear cut Cover 2 being played by TTUN.
#24 is a 5 star DB, Lavert Hill. #14 is a 3 star safety, Josh Metellus.
On this play when playing Cover 2 as a defense, (the corner) #24 has to stay outside the number 1 receiver and have eyes on the number 2 receiver. Also, if the number 1 receiver runs north, you get your hands on him to funnel him inside to make the safety's job easier to get to him and guard him. When the number 2 receiver proceeds to run north as well, you stick with number 1 and he becomes your man. #24 didn't do any of this and chose to guard grass.
Although #14, Metellus didn't stay as deep as a safety should in Cover 2, he's not the only one at fault for this TD.
Point is, TTUN goes on and on about getting better recruits to close the gap between us and them. They clearly have a 5 star DB critically messing up (as he did all game) and causing big plays by the opposing team (the good guys). The gap between us isn't just recruiting, its coaching, and this (as our defense from last year did) points to poor coaching by TTUN on defense.
