Five worst Week 13 performances: Questionable Kevin Stefanski calls, awful Texans-Colts officiating and more

Ka'imi Fairbairn's attempt appeared to cross wide of the left upright, but officials deemed the try successful, giving the Texans a 20-13 lead. 

Had officials ruled the kick no good, Indianapolis would have had a chance to tie the game with a field goal on its final drive. Instead, the Colts were forced to try to convert a 4th-and-9 from Houston's 31-yard line on their final play.

Martin didn't offer any satisfactory answers afterward, instead justifying the obvious mistakes.

Houston's excellent defensive effort holding the high-scoring Colts offense to a season-low in points should be the biggest story from Sunday's AFC South showdown. Instead, refs created a stain impossible to ignore.

Minnesota Vikings quarterback Max Brosmer

At least J.J. McCarthy doesn't have to worry about Bosmer taking his job. The undrafted free agent made his first NFL start in place of an injured McCarthy (concussion) and had a nightmare performance against the Seattle Seahawks in a 26-0 loss, the Vikings' first shutout defeat since 2007 and eighth in franchise history.

Bosmer was 19-of-30 for 126 yards and four interceptions while also losing 30 yards on four sacks. His worst throw came in the red zone while the game was still competitive, when he avoided a sack with an awkward throwaway and was intercepted by Seahawks linebacker Ernest Jones, who returned the pick-six 84 yards.

Los Angeles Rams quarterback Matthew Stafford

A leading MVP candidate, Stafford had his worst game of the season in an upset 31-28 loss at the Carolina Panthers (7-6).

Earlier in the game, he extended his record of touchdowns without an interception to 28 before regressing to the mean.

Stafford's first pick wasn't his fault, but it was costly nonetheless. The 17-year veteran's red-zone pass on a 3rd-and-6 was tipped and intercepted in the end zone, taking at least three points off the board.

Four plays from scrimmage later, Stafford forced a throw to wideout Puka Nacua into a tight window, and Panthers corner Mike Jackson picked the pass and returned it 48 yards for a touchdown.

Stafford also lost a fumble while being sacked late in the fourth quarter, keeping the Rams from attempting a tying field goal.

As much praise as Stafford has rightfully received for his incredible season, he deserves criticism when things don't go as well. But everyone has rough games. The Rams just need Stafford's to be a one-off.

Cleveland Browns head coach Kevin Stefanski

Stefanski made some confounding decisions in a 26-8 home loss to the San Francisco 49ers (9-4), dropping the Browns to 3-9.

Trailing 10-8 midway through the third quarter, Stefanski rolled the dice, keeping the offense on the field facing a 4th-and-1 from Cleveland's 33-yard line. He added unnecessary risk putting rookie tight end Harold Fannin Jr. under center for a potential QB sneak, but the Browns muffed the snap and San Fransisco took possession. The 49ers converted the short field into a touchdown nine plays later.

Afterward, Stefanski discussed the questionable play and said he "felt good about the call."

But that's not all, folks. Stefanski also used the game — rookie quarterback Shedeur Sanders' second career start — as a chance to experiment with his offensive line, rotating Wyatt Teller and Teven Jenkins at right guard.

There doesn't appear to be any rhyme or reason to Stefanski's decisions  — just a head coach biding time until he's given the pink slip.

Pittsburgh Steelers' second half versus Buffalo Bills

If Steelers fans turned off Sunday's game against the Bills at halftime, they likely had a lovely afternoon. Anyone watching the whole 60 minutes might need another television after throwing out theirs.

Pittsburgh expeditiously watched a 7-3 halftime lead go up in smoke on the first play from scrimmage of the second half, a sack-fumble on quarterback Aaron Rodgers created by Joey Bosa and returned for a touchdown by defensive back Christian Benford.

Backup quarterback Mason Rudolph was briefly forced into action after that hit and threw an interception on his second pass attempt, setting up another Bills touchdown.

Outside of one 57-yard drive that ended with a turnover on downs, the Steelers gained 21 yards on 11 second-half plays as they failed to regain lead of the AFC North before next Sunday's first of two regular season games with the rival Baltimore Ravens (6-6).
