It's worth wondering about...but also take a moment and note that those stats really aren't great for a half of football, esp. if your team isn't having success running the ball. It's a high completion percentage, but the YPA is very low. That kind of stat line suggests to me that your team is struggling to move the ball in large chunks, so you're checking down to the RB/TE a lot, throwing a lot of screens, etc. Easy, high-percentage completions with very little added after the catch. Plus you throw in a legitimate sack or two such that the passing game marches backwards a bit.
