Just want to say, that receiving is easy to learn in the NFL and blocking is hard.
In the last 5 years, WR has been the fastest-starting position in football. The handful of TEs who've got off to fast starts in the NFL tend to be utlized like WRs... Evan Engram, Mark Andrews, Kyle Pitts before Arthur Smith showed up, etc.
Blockers in the NFL rarely start fast, and blocking TEs almost never do. There's a strength gap between college and pros that they need to close. And also a communications gap, where they have to learn to diagnose more complex fronts than they've ever seen before and block them in synch with teammates they've never spoke to before. There is a reason why OLmen never rotate... that chemistry is hard to build.
LaPorta is being used heavily as a receiver, and he's been doing a damn good job of it. But receiving is the is the "easy" way for a TE to shine in their first 3 games. If your argument for guys like Schoon is "they're better blockers", it'll take a few years for that blocking to develop.
