The statistic you're reading from isn't one kept to illustrate how good the O-Line is, though lower sack numbers despite it is a positive. It is an indictment against the WRs or a view of how good the coverage is against the WRs. QBs are better the lower that number is, generally. The fact that Patrick is still performing at a high level despite his time to throw being higher is good, it's not that the time to throw being high is better.
Taylor and Trey Smith are both in the top 10 in penalties right now, in the NFL as a whole, not simply as offensive linemen. 7 of their combined 21 are holding penalties. Kelce has 5 more penalties and Donovan Smith has 4. Of those additional 9, 4 of them are holding. Creed also chips in with 2 more holding penalties. That's 13 accepted holding penalties on our primary blockers in 11 games. I haven't gone through and looked at every team in the NFL for comparison, but at first glance, it looks exceptionally higher than most. If that is the case, that moves us more to a middle-of-the-pack line in terms of negative plays.
What I can get on board with is the theory that if our WRs were uncovering more quickly and that time to throw went down, there would be fewer holding penalties and thus, fewer negative plays. No matter what though, Taylor and T Smith need to play better football.
