Hill vs Siemian why is there a debate?

Thing is has Trevor really ever had a chance? He was plying pretty decent in Denver until he was quickly benched for the new toy (Osweiler). Then bounced around as a backup. The kid has skills, but like Winston, this is probably his first stop where he has a coach who takes pride in putting his QBs in a position to win. Unless it’s a pride thing, After this weekend and probably blowing out Atlanta, it’s going to be really hard for Payton to bench him for Hill.
Yes, he had two years to start in Denver and got worse over time.

After the 2015 Super Bowl season, Peyton Manning retired and his back up, Brock Osweiler, signed with Houston because they were willing to pay way more than Denver. So Elway drafted Paxton Lynch in the first round (who was really terrible), but the coach was Gary Kubiak, who favored and started Siemian, who he had personally selected in the 7th round the year before.

Siemian showed he wasn't the answer, but the next year, 2017, they didn't sign anyone because they hoped that Lynch would be ready. But he was a complete bust and they were again stuck with Siemian, who had regressed. Eventually they did bring back Osweiler off the street (after he'd been traded to and then cut by Cleveland) because the situation between Siemian and Lynch was so bad. All three quarterbacks were gone after the season.

It is what it is. We had a great run with Brees, but we've entered quarterback hell. For a preview of what's likely in front of us, let's look again to Denver. Since Manning retired in 2016, they've had the following starting quarterbacks:

Trevor Siemian
Paxton Lynch
Brock Osweiler
Case Keenum
Joe Flacco
Brandon Allen
Drew Lock
Jeff Driskel
Brett Rypien
Kendall Hinton*
Teddy Bridgewater
