There is not a lot of proven depth, but the Purdue TEs should be better this year.
I expect the tight end position to have more production this season, mostly because TEs coach terry Malone moved up to take the reigns as offensive coordinator. He likely knows these guys best after coaching them for three seasons, so it makes sense for him to find ways to work them into the offense more.
Currently there are only four tight ends on the entire roster, and only one has even played in a game so far. That leaves a pretty clear starter.
