No. 2 Jaguars whose stock is down after Week 1 win vs. the Colts: Anton Harrison, OT
Although some rookies have an impact right off the bat, others struggle early on and need time to hit their stride. Others showed flashes followed by rough outings. In Anton Harrison's case, it looks like he'll need time to get acclimated to both the NFL and his new position.
A first-round pick in this year's draft, Harrison struggled in his debut against the Colts. He often lined up against Colts defensive end Kwity Paye and had a hard time containing him. Again, this is expected from first-year players, so it's not time to hit the panic button.
That said, Harrison's struggles made it difficult to run the ball. Similarly, Trevor Lawrence pressured a bit more than the Jags would've liked. Working in Harrison's favor is that he's the only offensive lineman that struggled in the opener. Right guard Brandon Scherff, who eventually left the game with an ankle injury, also had a hard time stopping the Colts' defensive tackles.
This is just one game and there's a reason to believe Harrison will be fine. Putting aside the fact that he just made his first NFL start, he mostly lined up at left tackle at Oklahoma but switched sides with the Jags. Once he gets used to his new position, he should come though. It may not be against the Kansas City Chiefs, or even the following week, but the tools are there for Harrison to excel.
