Then again, given the penchant for untimely self-destruction the Cowboys have displayed during Tulloch's eight-year career, something told him to keep hope alive.
"I thought they would take a knee on third down to drain the clock -- then kick a field goal, squib it, play prevent defense, make a couple of tackles inbounds and it's over," Tulloch said Sunday night, long after leaving Ford Field following perhaps the most entertaining game of the 2013 season. "But the Cowboys always find a way (to mess it up) -- you know that."
"Wasn't that (expletive) crazy?" Tulloch asked, his voice still rising with excitement. "This team fights every week, and we fight to the finish, but we didn't know if that chance would come."
Having given Detroit an opening with a horrid holding penalty, Dallas was done in by quarterback Matthew Stafford's moxie and receiver Calvin Johnson's peerless excellence -- not to mention its own chaotic sideline atmosphere and a growing sense of self-doubt. While the Cowboys (4-4), the NFL's poster children for mediocrity, remained atop the pathetic NFC (L)East, the Lions (5-3) closed the day a half-game behind the Packers in the NFC North.
Were the regular season to end today, both teams would make the playoffs, Detroit for the second time in three campaigns after a drought that dated to the 1999 season. And while a lot can happen between now and January, this was a sweet Sunday for the Lions, whose dramatic comeback triumph reaffirmed an internal sense that, despite an utterly forgettable 2012, they're capable of defying conventional wisdom and competing for a championship.
For a team whose coach (Jim Schwartz) and general manager (Martin Mayhew) are perceived to be in win-or-else situations in 2013, this was the type of improbable victory that can galvanize a locker room.
Had Garrett opted to have Romo kneel behind the line of scrimmage, Dan Bailey's field-goal try would have come from roughly 55 yards out -- and with a missed kick, Detroit would have taken possession at its own 45, needing only a field goal to tie. (Or, if Garrett had chosen to punt on fourth down, the Lions likely would have needed to go at least 50 yards in 30 seconds -- without a timeout -- to set up a potential tying kick.)
Instead, Garrett went with a handoff to halfback Phillip Tanner, who burst up the middle for 9 yards. That would have been a wonderful result -- had left tackle Tyron Smith not been flagged for holding. The clock stopped at 1:07 even after Schwartz declined the penalty, leaving Bailey to convert a 44-yard field-goal attempt for a 30-24 lead.
"When we saw the flag," Tulloch said, "we knew we had a chance."
After a touchback on the ensuing kickoff, Detroit took over at its 20 with 1:02 to go, and Stafford (33 of 48 for 488 yards on the afternoon), who'd previously given up two interceptions, delivered strong and accurate throws with the game on the line. After a 17-yard pass to Johnson and a clock-killing spike, Stafford found a hole in the Cowboys' Cover 2 zone along the left sideline and dropped a gorgeous dime to wideout Kris Durham, who got out of bounds following a 40-yard gain.
With 33 seconds remaining and the ball at the Dallas 23, there was little doubt Stafford would look Johnson's way. Sure enough, the game's preeminent receiver made his 14th catch of the day and was taken down 1 yard short of the end zone.
Then, after racing his team to the line for a clock-killing spike, Stafford made an executive decision: He took the snap and audibilized on the fly, lunging the ball across the goal line while catching the Cowboys -- and his teammates -- completely off guard.
"Matt, he (expletive) went over -- crazy," Tulloch said. "He made the sacrifice, cause he knew how much it meant."
It meant that -- after David Akers' extra-point kick with 12 seconds to go and one last, futile Cowboys play from scrimmage -- Detroit had pulled off a statistical anomaly: The Lions won a game in which they had given up four turnovers and their opponent had given up none, marking the first time that'd happened since the Patriots turned the same trick against the Dolphins in 2007.
If the Lions bucking that trend was enough to unhinge the Cowboys, who'd taken a 10-point lead on Romo's 50-yard touchdown pass to Dez Bryant with 6:45 remaining, well, Dallas was in the process of losing it even prior to blowing the lead. Bryant had a couple of sideline tantrums, one coming before his second touchdown catch of the day and the other after, that had to be defused by teammates and coaches.
One source of pressure might have been the realization that, after having said before the game, "I believe I can do whatever (Johnson) can do," Bryant was watching his Lions counterpart make him look silly, accumulating a ridiculous 329 receiving yards -- second only to Flipper Anderson's single-game NFL record of 336 yards for the Rams in 1989.
Conversely, Johnson -- at least, in Tulloch's estimation -- wasn't caught up in the comparison.
"Nah, man -- Calvin's not that kind of guy," Tulloch insisted. "He hates talking to the media. He doesn't buy into that crap. Even after the game, we gave him the game ball, and we yelled, 'Speech, speech, speech!' and chanted 'Calvin, Calvin, Calvin.'
"He said, 'Man, what do you want me to say?' He doesn't talk. He just works. I feel like telling him, 'Do you realize who you are, and what you're doing, and what kind of impact you're having on the game of football?' I wish there were more like him."
Before ending our conversation and heading happily into the Lions' bye week, Tulloch expressed another wish.
"Hey Mike," he said, "don't jump on the bandwagon now. We've been a good team now, brother, but most people didn't want to see that. They were all, 'They're no good. ... Fire Schwartz ...' and all that stuff. Now they want to talk us up cause we won a game? I hate when that happens."
Alas, that would be considered the NFL's version of a first-world problem -- as is the team's top-10 standing on our weekly best-to-Jax assessment of the pro-football mosaic:
16) Tennessee Titans: After Bud Adams' passing, why do I get the sense that FedEx founder Fred Smith would like to acquire the franchise via next-day delivery?
26) Houston Texans: Are ex-Texans rookies Sam Montgomery, Cierre Wood and Willie Jefferson merely misunderstood cigar aficionados, or were they getting their Cheech and Chong on in the team hotel last weekend -- and unwittingly creating a perfect metaphor for Houston's season?
