TCU and Iowa State struggled offensively to start -- scoreless through the first 20 minutes -- but both Big 12 teams eventually found their stride... literally.
Iowa State rushed for 213 yards on 28 attempts (7.6 yards per rush), while TCU threw for 400 yards.
For the Horned Frogs, it was a dual effort from quarterbacks Matt Downing and Max Duggan.
Downing, the Georgia Bulldog transfer, started the game and completed TCU's first touchdown of 2020 to true freshman receiver Quentin Johnson for 37 yards.
Johnson has big shoes to fill replacing former TCU superstar Jalen Reagor (now a member of the Philadelphia Eagles), but Johnson wore the #1 jersey well on Saturday with two catches for 50 yards and the touchdown in his college debut.
Downing struggled for much of the first half, though. The sophomore finished 11-21 for 159 yards and the one touchdown.
The Frogs trailed the Cyclones 16-7 at halftime.
Duggan, the incumbent starting QB, replaced Downing in the second half and immediately provided a jolt to the TCU offense.
The sophomore racked up 241 yards passing in just one half of football and completed 16 of 19 passes for three touchdowns and one interception.
Duggan completed all three touchdowns in the final 15 minutes and 23 seconds, including the final play of the game -- a 31-yard pass to Blair Conwright.
TCU elected not to kick the extra point since the game was over and impossible to win.
Cyclones prevailed 37-34.
The last-second touchdown did not impact the outcome for TCU or Iowa State, but it had some *additional* implications too.
Iowa State was favored by 2.5 points most of the week before closing at 3.5 points at some sportsbooks.
Depending on what side of the wager they were on, the last-second TCU touchdown made a lot of folks happy or sad.
And the decision not to kick the extra point made even more folks happy or sad.
TCU could not stop Iowa State's rushing attack and the Frogs rally fell short.
It's the first home opening loss for TCU since 2013 vs. LSU.
Next up for TCU: at Texas on Sat., Oct. 3 in Austin. Gametime TBD.
