Pitts was a lazy dude coasting on elite athleticism, athleticism that he permanently lost after a knee injury in year 2. After that he was a TE who can't block, or get open in the passing game. Every coach and QB Pitt's has had since year 1 has been subtly referencing his terrible work ethic in off season interviews. Even milquetoast Kirk Cousins was basically asking him to stop running his routes half speed.
Jonnu Smith has proven to be a better player than Pitts on multiple teams. Last year Pitts lost out to Ray-Ray McCloud in the target pecking order because of how bad he was. Pitt's is starting to look somewhat serviceable (still a shadow of what he was), in what do you know, a contract year.
I get that wasn't your point, MHJ isn't Kyle Pitts of course. But if he ever lost his traits the same way Pitts did, the only real way to force it to a player like that is to recreate the Rondale Moore bubble screen game.
