All these are good points and make sense.I think it depends on whether Gattis returns. Offense hasn't been a good fit so he may take his chances of falling significantly in draft to leave early. Yes Gattis might have made some adjustments 5 weeks into the season, but it took so long that TVDs draft stock took a big hit. He might be a bit salty over that and I wouldnt blame him. If we get a more spread oriented OC, TVD might stay because I think he could put up tremendous numbers and really help his draft position. Garcia probably leaves though.
IMO - TVD has plenty of time to get over that slow start. TVD's last 6 games last year made everyone forget all about his first 2 starts which weren't good.
NFL vs Staying is a complete roll of the dice either way.
NFL - Where players are projected in January can change a lot by April. And where players are projected on the day of the draft may still be completely off. Sometimes there's slides like Malik Willis & Sam Howell last year. A couple years ago Jordan Love & Jalen Hurts go higher than projected.
Staying in College - It's just as much a roll of the dice IMO. Let's say we get a new OC next year. I'm sure TVD thought Gattis was going to work out better than he has so far, right? Although they've hopefully righted the ship. But you have to declare for the draft mid-January. Lashlee was hired Jan 3. Enos Jan 11. Gattis Feb 6. TVD would likely have 2 weeks or less to decide whether or not the new OC is a better gamble than going pro. Short time for a big decision.
