The Cold, Hard Football Facts CORE PLAYS are off to a great start, especially regarding prop plays. We went 7-3 last Sunday with props, and we have some strong leans this week based on our proprietary stats. 

Christian McCaffrey is one player who has continued to impress this season. He has been a dominant running back and performed against some of the best defensive fronts in the NFL. As talented as McCaffrey is, the 49ers offensive line has been the primary reason the running back has performed so well. 

San Francisco's offensive line was a question mark heading into the season, but they have exceeded expectations thus far. The team ranks third in Offensive Hog Index, and fourth in Offensive Rusher Rating. 

The combination of the offensive line talent and McCaffrey has helped the team rank third in the NFL in rushing yards per game. We expect their ground dominance to continue on Sunday against the Cardinals, especially after ten days of rest. 

McCaffrey carried the ball 18 times for 85 yards with a touchdown last Thursday against the Giants. This marked the third straight game in which he exceeded his rushing total. He has also surpassed his combined rushing and receiving total in all three games. 

His rushing total is listed at 78.5, and his combined number is 110.5 on Sunday. We like him to go over both prop bets against Arizona. The Cardinals have made a valiant effort this season, starting with a 1-2 record. 

Arizona ranks 21st in Defensive Rusher Rating, so San Francisco has a massive advantage. The Cardinals also are 18th in Defensive Hog Index, so the 49ers' offensive line should be able to enforce their will throughout the game.
