The Dallas Cowboys apparently did do something right in 2019.

Pro Football Focus released an interesting statistic this week, noting that the Cowboys' offensive line allowed just eight sacks on the season, which was the best in the NFL.

Now, it should be noted that this does not mean Dak Prescott was only sacked eight times, because he was sacked 23. What it means is that 15 of those sacks were not surrendered by the offensive line itself and/or that the offensive line was not at fault for them.

It seems like a rather arbitrary statistic, but when you really take it into consideration, it's actually pretty important. Because it demonstrates that Dallas' offensive line remained strong point this past year.

Of course, that was also one of the few bright spots for the Cowboys.

Pegged as a darkhorse Super Bowl contender by some entering 2019, Dallas certainly played the part early on, winning its first three games and looking downright dominant in doing so. But once the schedule started getting tougher, the Cowboys began to struggle.

Following their 3-0 start, Dallas went just 5-8 the rest of the way, losing what was essentially an NFC East-deciding game against the injury-riddled Philadelphia Eagles in Week 16.

The fact that the Cowboys did not make the playoffs in spite of having one of the league's most talented rosters top-to-bottom was pretty mind-boggling, but many felt that head coach Jason Garrett was the main problem.

Apparently, Jerry Jones and Co. felt a similar way, as Dallas finally parted ways with Garrett earlier this offseason after he spent a decade at the helm.

The Cowboys hired Mike McCarthy as Garrett's replacement.
