DJ is above average.
He was 39th in the country in passer rating.
12th in total QBR.
20th in PAA, which is literally points scored over a dead average QB.
28th in EPA.
He's not bad. But he's not great, and he doesn't elevate your team at all. Oregon State went 8-4 last year. They went 9-3 the previous season. He got benched several times in 2022 and they had to turn to a true freshman.
Point blank, he's a downgrade from Travis. And more so, he can't turn and hand the ball to Tre Benson (Likely a Day 2 NFL pick), nor throw it to Jonny Wilson, Keon Coleman, or Jaheim Bell. Sure, there will be replacements for those kids, but will they be the same level? HIGHLY doubtful. So they're worse at QB and their weapons are worse. Maybe not off a cliff worse, but indisputably worse.
