McCaffrey had a season for the ages in 2019, posting the third most scrimmage yards in NFL history (2,392) and falling only 118 shy of setting a record. With Cam Newton out for most of the year, CMac became the unquestioned focal point of the Panthers' attack, racking up a dizzying 403 touches and topping 100 receptions for the second consecutive campaign. He wasn't just an open-field weapon, though. McCaffrey saw 20 carries inside the 5-yard line, good for second in the NFL, and that goal-line usage led to a career-high 15 rushing TDs. The question heading into 2020 is how much that workload will affect his efficiency. McCaffrey's elite elusiveness and speed have allowed him to avoid a lot of big hits, and he has yet to miss a game in his career, but the history of running backs coming off massive workloads is checkered at best. Even within the context of last year he showed a possible weakness, as he managed just 1.8 yards per carry after contact, eighth fewest in the league and a drop from the 2.1 he posted in 2018. That said, Carolina's new-look offense with Teddy Bridgewater under center and former Saints assistant Joe Brady as coordinator should be just as committed to getting McCaffrey the ball in optimal situations, and the front office didn't make him the highest-paid running back in the NFL without expecting plenty of production in return.

A September ankle injury cost Barkley any chance of repeating his phenomenal rookie numbers, but when he was fully healthy he proved that his 2018 production was no fluke. Arguably the greatest big-play threat in the league, Barkley averaged 5.2 yards a carry in the six games following the Giants' bye to close out the season, and despite only being in top shape for about half the year he still recorded five gains of at least 40 yards while finishing in the top 10 in rushing yards after contact. At 5-11, 233, Barkley's unreal blend of power, speed, elusiveness and receiving skill is basically unparalleled, but he's needed every ounce of that talent working behind an offensive line that was awful in 2018, and merely below average last season. If the Giants continue to rebuild the unit in the draft, and quarterback Daniel Jones emerges as a weapon in his own right, Barkley could finally have a supporting cast worthy of his talent. New offensive coordinator Jason Garrett knows how to feed a bell cow from his days in Dallas, as Ezekiel Elliott has averaged nearly three more touches per game than Barkley in their respective careers, so volume should not be an issue in the team's new scheme. Don't be surprised if Saquon's rookie production ends up being his baseline rather than his ceiling.

Elliott played a full 16-game schedule for the first time in 2019, a remarkable achievement considering he sat out all training camp and preseason in a contract dispute. Once he had a new six-year extension in his pocket, Zeke resumed his role as the focal point of the Dallas offense and barely missed a beat, finding the end zone in six of the first seven games en route to 1,777 scrimmage yards and 14 TDs. Elliott simply does everything well, but it's his ability to handle a huge workload that might be his most impressive attribute. He led the league in red-zone rushes (59) and tied Aaron Jones in TDs from inside the five with 10, and only Derrick Henry saw more than Elliott's 301 total - the third time in four seasons Elliott has topped 300. The Cowboys' offense heads into 2020 facing some significant changes, however. Gone is long-time coach Jason Garrett, and while offensive coordinator Kellen Moore remains, new head coach Mike McCarthy is likely to favor a more pass-friendly scheme than the conservative Garrett. Perhaps more important, five-time Pro Bowler Travis Frederick retired, leaving Joe Looney as the starting center. Elliott posted strong numbers in 2018 when Frederick missed the entire season, but the combination of uncertainty in front of him and a potential loss of touches could prevent Zeke from producing at an elite level again.

The 2019 campaign was a relative disappointment for Kamara, as lower-leg injuries hampered his effectiveness down the stretch and limited him to "only" 1,330 scrimmage yards and six TDs, the lowest totals of his three-year career. When he's in top form, the Tennessee product remains one of the most electric open-field runners in the league and one of the top receiving threats out of the backfield, and he's remarkably hauled in exactly 81 passes in each of his three seasons. Before the injuries began to slow him, Kamara was right on pace for another brilliant campaign, averaging 7.1 yards per target through his first six games but only 4.3 YPT over his last nine, including the playoffs. Karama's secret weapon has always been his surprising power and sturdiness as a rusher at 5-10, 215. Even in a season when he was often performing at less than 100 percent as he gutted out his injuries, he led the league in broken tackle rate with one for every 5.9 carries. Latavius Murray is still in town as a solid, veteran backup who can handle double-digit touches a game to help keep Kamara fresh, but there's no question who the No. 1 option is when both backs are healthy.

Cook stayed mostly healthy in 2019 and as a result put together a career season, but his improved numbers were more than just a product of increased volume. The Florida State product solidified his standing as a three-down weapon, leading the NFL in carries inside the 5-yard line with 21 while also finishing second to Austin Ekeler (9.2) in yards per target among RBs at 8.2. Cook's burst through the hole and speed in the open field remain his greatest assets, and his well-rounded skill set keeps him on the field in most situations and makes him arguably the key figure in a Minnesota offense that finished fourth in the NFL with a 48.3 percent run-play rate. Despite the dynamic numbers, the 5-10, 210-pound Cook still isn't completely free of his injury-prone reputation, as the team sat him for the final two games of the regular season while he nursed a shoulder injury, before he scored twice in an upset win over New Orleans in the opening round of the playoffs. With a reliable backup available in Alexander Mattison, the Vikings likely will continue to keep a close eye on Cook's workload, and it would be surprising if he saw a significant increase in touches in 2020.
