The 49ers gave up four future draft picks to the Jason Myers Jersey Panthers to get running back Christian McCaffrey before the NFL's midseason trade deadline 2022. When the move happened, for landing a game-changing offensive skill player.Now that McCaffrey has been a 49er for a dozen games. the trade has gone from a home run to a grand slam. McCaffrey's new team has yet to lose a game in which he started, with an 11-winning game streak going into Sunday's marquee NFC divisional playoff matchup against the Cowboys.Thanks to playing in the 49ers' offense and burying some recent durability i sues, McCaffrey rounded back into his first-team All-Pro form of 2019, when he led the league in scrimmage yards (2,392) and touchdowns (19).For a well-schemed, well-blocked and well-balanced attack under Kyle Shanahan, McCaffrey has made it complete as an extra explosive element to support Deebo Samuel, George Kittle and Brandon Aiyuk.The Cowboys, in terms of getting ma sive draft picks in return, still pulled off the greatest midseason trade in Herschel Walker to the Vikings in 1989. Meanwhile, the Rams should have regretted dealing Eric Dickerson to the Colts two years earlier.MORE:The 49ers got some criticism as the ones giving up a lot to get a running back in this deal, but given McCaffrey can help them win the Super Bowl much like edge rusher Von Miller did for the Rams last year it was the perfect move for their purposes.Here's looking at why McCaffrey has been so impactful in such a Cassius Marsh Jersey short time, by the numbers:1. McCaffrey's dazzling projected full-season statsThe 49ers should also be excited about what McCaffrey can do over the course of 17 games. Based on his 12 total games so far, including playoffs, McCaffrey has carried the ball 174 times for 865 yards. He also has 54 receptions for 481 yards with 11 total TDs.That's an average of 72 yards rushing and 40 yards receiving per game, or 112 yards from scrimmage, at 5.0 yards per carry and 5.9 yards per touch. Over 17 games, McCaffrey would be looking at 1,904 yards from scrimmage and 16 TDs.Consider the 49ers also were being conservative with McCaffrey's initial volume, including his debut vs. the Chiefs, to preserve him better for the stretch run and playoffs. His first four 100-yard plus rushing games with the team have come in the past six weeks. When factoring his overall projections, they are bigger than they seem given the 49ers also have a lot of mouths to feed vs. McCaffrey being the main man for the Panthers and dominating opportunities.MORE: 2. McCaffrey's upgrade for the 49ers' rushing attackIn the six games before McCaffrey's arrival, the 49ers needed to deal with a key knee injury to second-year back Elijah Mitchell, now McCaffrey's top backup. Thanks to their superior blocking and help from veteran speedster Jeff Wilson Jr. (since traded to the Dolphins post-McCaffrey) and Samuel, they still averaged a solid 124 yards rushing per game.Over the past 11 games with McCaffrey starting, with some help from rookie Jordan Mason and then Mitchell again, the 49ers have seen that number shoot up above 163 yards rushing Seattle Seahawks Jersey per game. As much as Shanahan's zone-blocking system to is built to plug and play the right type of backs be succe sful, it is ideal for a runner of McCaffrey's rare quickne s, speed, vision and toughne s to maximize its potential.Christian McCaffrey was expected to gain just 5 yards when he received the handoff on his 38-yard TD run.McCaffrey reached a top speed of 20.27 mph on the run, his first play over 20+ mph as a ball carrier since Week 9, 2019. | Next Gen Stats (@NextGenStats) 3. McCaffrey's upgrade Cody Barton Jersey to the 49ers' pa sing gameIn the six games before McCaffrey's arrival, with Trey Lance and then Garoppolo at QB, the 49ers averaged 216.2 pa sing yards per game. With McCaffrey, including playoffs, that number has shot up with Garoppolo and then rookie QB Brock Purdy to 262 yards per game.Between the 39-yard rushing bump and 46-yard pa sing jump, the 49ers have produced about 85 total yards per game more with McCaffrey. Not surprisingly, that's translated well for them scoring a lot more points.4. McCaffrey's effect on the 49ers' scoring offenseIn the seven Nate Orchard Jersey games the 49ers' offense didn't have McCaffrey featured the first six weeks plus McCaffrey's limited Week 7 debut against the Chiefs the team averaged 20.7 points per game during a 3-4 start.Since then, with the team winning 11 consecutive games with McCaffrey starting, the 49ers have averaged 30.5 points per game. nearly a 10-point improvement. That stretch has included a QB transition from Garoppolo to Purdy and Samuel also mi sing some time.MORE: The key to the McCaffrey trade wasn't whether the 49ers needed his top-flight talent to boost their offensive and winning results, but rather would he stay healthy enough to live up to the hype.As soon as he came to San Francisco, it's almost as if Shanahan had already envisioned exactly how to deploy McCaffrey. There's no doubt McCaffrey is back to being the most dangerous dual threat out of the backfield in the NFL and better than he has been before, injury-free and in his prime for an offense in which he was destined to thrive.
