San Francisco 49ers vs Indianapolis Colts Props & Analysis
With two offenses featuring high-profile skill players, the prop market is buzzing with opportunities. The visiting San Francisco 49ers average 24.3 points per game, while the Indianapolis Colts put up a potent 27.7 points per game. Let’s look at some of the key player props available for this matchup.
The rushing markets for this game are particularly compelling. The number for Indianapolis Colts running back Jonathan Taylor is set at 104.5 rushing yards, a number that aligns almost perfectly with his season average of 103.1 yards per game. Taylor has been a workhorse, averaging an impressive 5.31 yards per carry and finding the end zone for 16 rushing touchdowns this season, making his TD market at -231 a popular, albeit heavily juiced, pick.
On the other side, Christian McCaffrey presents a fascinating case for his total yardage number. The number for his combined rushing and receiving yards sits at 106.5. This season, McCaffrey is averaging 65.86 rushing yards and 58.57 receiving yards, for a total of over 124 scrimmage yards per game, suggesting strong value on higher. For the quarterbacks, Brock Purdy’s passing yards number is 246.5, just slightly above his per-game average of 240.3 yards. Meanwhile, Colts quarterback Philip Rivers has a line of 161.5 passing yards, though in his single game appearance this season, he posted only 120 yards.

When building your lineups, you have a couple of strategic options. A Standard entry requires you to get all your picks correct (minimum of two) to win, but it offers the largest payout. Alternatively, you can choose a Flex entry (minimum of three picks), which provides a safety net. With a Flex entry, you can still receive a payout even if one of your picks is incorrect, making it a great option for larger parlays.
