I hope you are right but I don't have the same faith in MHJ as you.
It's not faith, it's understanding that he is not getting opportunities.
Here is where MHJ ranks.
55th in the NFL in targets.
51st in the NFL in yards per target.
62nd in the NFL in receptions.
34th in the NFL in yards per reception.
61st in average depth of target.
Consider this. Kyler has attempted three passes deep to MHJ. One was a 45 yard completion vs the Saints. One was almost a huge play vs the Saints. The third was a 38 yards pass interference. Those aren't outcomes of a bad or mid WR. Only an incompetent OC like Petzing wouldn't' emphasize this more.
