I'm not disagreeing with most that is said in here, Auburn got a rather lucky win last night and offensively didn't do much.
But at the same time when people pick on Marshall and his passing skills and point out, that KState could have easily won (missed FGs etc), they should also remember that Auburns WR dropped several easy catches incl. one perfectly thrown deep ball by Marshall, that would have went for a TD. Several others were dropped and instead of giving Auburn a 1st down, put Marshall and Auburn into 3rd and long and obvious passing situations, so to me the problem was more their receiving corps than Marshall last night.
Marshall had two really bad passes that were tipped at the line of scrimmage incl. the one that got intercepted and overthrew two WR deep, that could have scored if he had hit them. But those deep balls were barely overthrown and still better to overthrow, than to underthrow them in that situation. Besides those two deep balls, he hit his targets for most part in rather difficult wind conditions.
But if I was a Auburn fan, those drops would concern me because it's more a lack of concentration than anything else and shouldn't happen in week3 in a close game to boot. And their defense would make me doubt their postseason chances: Yes, it's a bend but don't break type of D, but last night it was more KState beating themselves than Auburn not breaking (besides the 3 missed FGs, the INT in the endzone should have been a TD. It wasn't a good defensive play but a WR mistake that caused that pick). And they didn't create any pressure with their pass rush, which caused KST WRs to get open regularly without many problems. Also lots of extremely soft coverage, basically giving up 5-8 yards on purpose, gifting 3rd and short to KST.
