There was a Kyle Meinke piece back in April in which Borges talked about this particular aspect of the transition in offensive philosophy and how they've recruited to it (LINK).
"I’m a tight end kind of guy," offensive coordinator Al Borges said this week. "I tell guys when we recruit them, when this thing’s working the way it should work, you’ll think you've died and gone to tight end heaven."
He also talks about how he tried to carefully define the roles of Williams and Funchess last year so that they did not get overworked at the position, but he seemed very optimistic about the possibilities at TE this year. He also discusses how he wants (and has been working towards) a position group whose players can catch a pass up the middle but also block well. This thread made me remember this article for some reason.
