Mr. "Get Open" caught a total of 13 passes in his first two seasons. He didn't score a TD until his 3rd season. Someone had to teach him how to get open.
Both rookie TE's have caught 2 TD passes. One has a running TD. Obviously, they are more trusted than Schultz when he first arrived
Since both rookie TE's handled the ball more at least as much as Dalton's first two seasons combined, I don't think it's unreasonable to assume that they may also learn how to get open. However, i have to say, they are much farther along than Dalton was as a rookie.
