Two of those players are true freshmen...TE is a position that usually doesn't give you a ton in their first year...some even their second year. Its a position that requires a lot of growth. To Dawson's credit, he's working Riley Williams in, and Riley Williams is obviously talented, but he's still got work to do and probably shouldn't be out there as much as he is. Carver was more raw than even Williams. Skinner isn't even a TE. More of a WR and if he's not playing, its likely for a reason...he likely isn't that good.
And, he IS getting something out of Riley Williams and Cam McCormick...McCormick as a blocker is one of our trump cards...Riley Williams has had moments (GaTech game).
Do we want more out of the position room right now statistically? Obviously...but that requires somebody to step up. No one has done that yet. So, other people get the ball. Its not an offensive coordinator issue, its a personnel issue.
