At present, Schultz is playing far above "JAG" level. I'm actually puzzled as to why you'd say that about him. He's getting open at a very high rate and has shown tremendous YAC ability.
I don't know how to make it any simpler. I couldn't possibly care less about his receiving skills, as I've stated in the past. He's decent. Not great, but does a good job. It would be near impossible for the vast majority of TE's to NOT get open with the depth we have at WR. They don't put the best CB on TE's typically. They certainly don't vs. Schultz. I wouldn't describe his performance as tremendous. He's good.
What I prefer is a better run block pass protector. Especially when we're short on OL depth. And we are and will be for a few weeks. This would help where we need it - At the line and in the red zone.
