Here's the data on TE usage as defined by receiving yards. Which years do you like? What have OCs done right or wrong? Note, ARod has been the OC for just over half this time. For simplicity's sake, I'm only including the leading (by yardage) QB, TE and WR. In seasons where our leading receiver was a TE (the Bushman years), they are listed first.

2014 (Bronco 8-5): Christian Stewart leading passer (2621 yds), Mitch Matthews WR (922 yds), Devin Mahina TE (244 yds)
2015 (Bronco 9-4): Tanner Mangum (3377 yds), MMathhews WR (737 yds), Moroni Laulu-Pututau TE (112 yds)
2016 (Kalani 9-4): Taysom Hill (2329 yds), Nick Kurtz WR (541 yds), Moroni Laulu-Pututau TE (277 yds)
2017 (Kalani 4-9): TMangum (1540 yds), Matt Bushman TE (520 yds), Aleva Hifo WR (437 yds)
2018 (Kalani 7-6): ZWilson (1578 yds), MBushman TE (511 yds), AHifo WR (358 yds)
2019 (Kalani 7-6): ZWilson (2382 yds), MBushman TE (688 yds), Micah Simon WR (616 yds)
2020 (Kalani 11-1): ZWilson (3692 yds), Dax Milne WR (1188 yds), Isaac Rex TE (429 yds)
2021 (Kalani 10-3): Jaren Hall (2583 yds), Puka Nacua WR (805 yds), Dallin Holker TE (200 yds)
2022 (Kalani 8-5): JHall (3291 yds), PNacua WR (625 yds), Isaac Rex TE (326 yds)
2023 (Kalani 5-7): Kedon Slovis (1716 yds), Chase Roberts WR (573 yds), Isaac Rex TE (422 yds)
2024 (Kalani 10-2): Jake Retzlaff (2794 yds), CRoberts WR (841 yds), Keanu Hill TE (108 yds), Note final game is still pending, but expect trend to continue.

There are probably more sophisticated analytics out there than what I could find on Cougarstats, but in this decade-long sample, it seems like emphasizing the TE is one of the least productive things you want to do for offensive production and team success. If your leading TE has the most yardage on the team, or even close to it, then you've probably been on the struggle bus. Don't believe me? Ask Utah what offensive position they're most proud of lately.
