I've bet Saquon Barkley Over 13.5 receiving yards. This year - SB has 7 games over the number and 12 under, including 1 over and 2 under in the playoffs.
But in Philly's 3 losses, he went well over the number in 2 of those losses - the exception being the loss to Washington, where Philly was up by 21 and Wash came back in the 4th Q scoring 23, after Hurtz knocked out of the game. SB also went over in the one close playoff game against LA. In other words, when Philly is being challenged by the opponent - the need to include throws to SB appears to rise, which makes sense. If Philly has a comfortable lead, as often is the case, you just hand him the ball.
Moreover, Philly will be game-planning for the KC blitzes, where tossing to SB in a one-on-one set-up will be an easy choice for Hurtz and no doubt will be part of Philly's game preparation and planning. Bills RB James Cook had his highest receiving yardage (49) in the championship game against KC on 3 receptions. It only takes one reception for SB to beat the number, and again, in a tight game against KC blitzes, I think it will be a natural part of the Eagles' game planning.
Good Luck!
