Drops/catch rate are a big part of the problem. It means that most of the time we throw to MHJ, we get 0 yards. Hard to move the chains when that happens. In order to give MHJ more targets he we need to reduce McBrides targets, why would we do that if MHJ has a terrible catch rate?
MHJ has a 22.2% target share and McBride has a 29.6% target share. For example, in another highly concentrated offense, Jamar Chase gets 27% of the targets and Tee Higgins 24.9%. You cant realistically concentrate an offense more than that, its just bad football.
Maybe you're thinking its all usage, if MHJ has trouble catching the deep stuff, maybe give him more short stuff? The problem there is he's terrible at breaking tackles and getting YAC. That was something he couldnt even do in college while beating up on the sisters of the poor.
I think a lot of people just don't realize how little we actually pass in general. 20% of 25 dropbacks is 5 target. Meanwhile the Bengals dropped back to pass 42 times last week. Higgins actually only got 4 targets in that game, while his usage last year would predict at least 10. Higgins turned his 4 targets into 51 yards and a TD. Marvin turned his 5 targets into 27 yards. This is a small sample to illustrate something that holds true if you look at larger samples, Tee Higgins is a better WR than MHJ.
If our defense collapses due to the CB injuries, and our run blocking continues to be terrible, maybe we start seeing Kyler drop back 40-50 times a game. If that happens, Marvin "inefficiency" Jr. might start seeing fantasy stats (PPR scam). I personally dont want to see Kyler dropping back that much. But just know this, if MHJ was as good as everyone here wants him to be, he would be able to produce with the 20-22% target share he currently has, even in a low pass volume offense. If that starts happening I would be fine with him stealing some of McBrides targets. But right now, MHJ is a painfully average player and McBride is an elite player, who deserves an elite target share.
