The fifth-ranked Tigers' 359 total yards marked the fewest Auburn has produced in 17 games under Malzahn. Marshall entered the season on many short lists of potential Heisman Trophy candidates after leading the Tigers to the national title game, and his coach said he's still coming through by the most important standard.
''The bottom line is our quarterback wins, he knows how to win,'' Malzahn said Tuesday. ''If you compare him to all the other quarterbacks around the country when the game's on the line we got the best guy. He'll continue to work but we have a lot of confidence in him.''
Against Kansas State, Marshall passed for 231 yards and rushed for 46 but threw an interception and had several throws deflected at the line. The receivers also had some drops in the 20-14 victory and Malzahn's offense didn't look nearly as unstoppable as it did late last season.
Marshall, who was suspended for the first half of the opener against Arkansas, isn't ranked among the Southeastern Conference's Top 10 passers going into Saturday's game with Louisiana Tech. He has completed 55.4 percent of his passes for 382 yards.
''I know for whatever reason the focus is always on our quarterback and, `What's wrong with Nick?''' Malzahn said. ''There's not a whole lot wrong with Nick. There's a couple things that we expect him to be really, really good at and if we're not we're going to get on him, but what the casual eye doesn't see is everything around him needs to be right. Need to be at the right depth, we need to have the right protection, everything needs to be right.''
Auburn's hurry-up offense didn't really hit its stride last season until after a switch to a heavy reliance on the zone read following the lone regular-season loss, to LSU.
Malzahn and offensive coordinator Rhett Lashlee are harping on fixing execution not making big changes this time.
Marshall is the first starting quarterback Malzahn has had return for a second season as a college coach, so he already knows well the things he does best.
When Auburn needed a first down to run out the clock in the final minutes, Auburn let Marshall throw. The result was a 39-yard completion to D'haquille Williams on third and 9.
The Tigers were limited to 128 yards on the ground, the second-fewest of the brief Malzahn era behind the Mississippi State game in 2013. Tailback Cameron Artis-Payne produced just 63 yards on 22 carries.
Lashlee's blunt assessment: ''Well, we didn't execute worth a crap.''
''We just didn't play well,'' he said. The Wildcats ''had a lot to do with that, but when you watch the film, on almost every play you can say, `That's not what we do. That's not our brand of football.'
''The big positive is we can learn from a win against a really good team on the road. Any time you win on the road against a good team, you'll never take it for granted. You'll be very happy with that, but it felt a lot like the Mississippi State game last year.''
That's when Marshall passed for a career-high 339 yards to compensate for a sputtering running game. After the next game, Auburn revamped its approach and the offense wound up leading the nation in rushing.
This time, Malzahn can take it as a victory of sorts that Auburn got the win even without the offense not at its best.
''Last year at this time, we wouldn't have won that game,'' he said. ''But our guys found a way to win and in some areas it was a good wake-up call.''
