ARLINGTON -- It was the play that could've doomed the Cowboys' season. Instead, the Cowboys shook of a horrifying play at the end of the half and rallied for a 28-17 win they absolutely had to have. Thousands of Chiefs fans who'd been silent for most of the first half erupted as quarterback Alex Smith completed a short pass to Tyreek Hill that he turned into a 56-yard touchdown on the last play of the half. It brought the Chiefs to within 14-10 and it left the home crowd stunned. The play highlighted Hill's uncanny speed and quickness, but also shed light on a Cowboys secondary that CBS analyst Tony Romo basically called slow at one point Sunday.

"I've never seen that in my entire time in football," said Romo. "And I promise you Jason Garrett hasn't, either."

It changed the complexion of Sunday's game, but the Cowboys responded once they fell behind, 17-14. They now face an uncertain future with Zeke Elliott's future tied up in court and Dez Bryant and Sunday's MVP Terrance Williams suffering leg injuries late in the game. Now, it's time for my Hurry-Up Postgame Column, which somehow doesn't yet have a sponsor:

** What an embarrassing sequence of events for Cowboys safety Byron Jones late in the first half. It was his unnecessary roughness penalty that gave the Chiefs decent field position to try to make something happen. Then he was penalized 15 more yards for immediately removing his helmet for no apparent reason after Hill's touchdown. That penalty set up the Chiefs with great field position to start the second half. Jones is fortunate his mistakes didn't cause the Cowboys to lose.

** Dak Prescott has added another dimension to his game this season with his running ability. We always knew he could extend plays, just as he did on a deep ball to Terrance Williams in the first half. What teams can't seem to defend is when Prescott fakes it to Elliott and then takes off himself. His quarterback draw on third-and-3 in the third quarter set up an Elliott touchdown. The two complement each other perfectly, which makes you wonder if the Cowboys can continue to flourish if Elliott has to serve this six-game suspension. The one thing I'll say on that front is that Alfred Morris will be extremely fresh. When he finally got a carry Sunday, he bulled his way for 11 yards with a defender on his back. Morris and Darren McFadden could be one of the most rested duos in league history.

** I was able to catch some of Tony Romo's work in the second half. He went after one of his most vocal critics, Deion Sanders, while discussing Chiefs cornerback Marcus Peters.

"He makes Deion Sanders look good at tackling, sometimes," said Romo. His broadcaster partner, Jim Nantz, laid out on that one.

** Cowboys defensive end DeMarcus Lawrence was active, but he didn't record a sack for the first time this season. David Irving had a huge sack once the Cowboys took a 21-17 lead, though. On third-and-11, Alex Smith tried to step up in the pocket and Irving was waiting on him. And with the Chiefs desperately trying to get something going later in the fourth quarter, rookie defensive end Taco Charlton registered the first sack of his career. He appeared to be dressing a taco in his celebration. This is somewhat similar to Cole Beasley's touchdown celebration in which he appears to be involved in food preparation. Beasley had two touchdowns Sunday and that gives him 4 TD's for the season.

** Terrance Williams had one of the best games of his career with nine catches for 141 yards. He continues to be adept at spinning away from defenders after making the catch. He also alertly stayed in bounds late in the game to keep the clock moving. He infamously didn't get out of bounds late in the first Giants game last season. Williams and Bryant both suffered leg injuries. Bryant suffered an ankle injury and didn't return to the game. Williams grimaced after he was tackled in the fourth quarter. The Cowboys need both of those players on the field, in part because of the potential loss of Elliott.

** The much-maligned safety Jeff Heath finished off the Chiefs when he picked off Alex Smith in the fourth quarter. He drove on the ball and made a great play. It really seems to work best for the Cowboys when Heath and Xavier Woods are sharing time. On special teams, Kavon Frazier and James Hanna both made tremendous plays. The Cowboys kept the Chiefs pinned in their own territory, in part because the special teams kept close watch on that dangerous Hill. Maybe some of those players should be on the field before end-of-the-half plays.
