* - Mustangs scored 80 first half points & a dominate defense that saw Prosser score via a Riley Lusk punt block for six, a Kason Blair INT return for six & two fumble returns for six by Ryan Merritt & Logan Hamlin.
** - Once again the Mustang D got in to the scoring column as Kolby Swift returned a fumble return for six, Noah Flores had a 82 kickoff return for six & Javier Diaz had a 80 yard punt return for six.
*** - In a game with a total of 74 yards offense from both sides, the Mustang D came through in a big way with 4 INT's, a 2 yard fumble return for six by Eddie Zepeda & a 35 yard INT for six by Javier Diaz for the win.
**** - Tanner Bolt's 4 TD passes combined with a lock down defense that limited the Bulldogs to 133 total yards & 4 INT's gave the Mustangs the win.
***** - In fitting fashion the Mustang D came through again as Kolby Swift caused the fumble and Riley Lusk recovered the ball with 30 secs remaining for the win.
