But so far, Bagley has been one of the newcomers to stick out for the Cardinals.
The 6-foot-3, 180-pound Bagley, who only played two years of organized football in high school, made some nice catches on day one and continued to impress on day two of the newcomers sessions with the Cardinals.
"He reminds me a lot of a young Harry Douglas," Petrino said. ". . . he's going to be fun to watch in the future because he's going to be really good."
Bagley had made some freshman mistakes, slipping on a few cuts and missing a couple of blocking assignments but the staff - and Petrino - remain high on his potential.
"I am trying to get all the plays down," Bagley said. "I feel like I am doing a good job, but I still have a ways to go. Coach Petrino runs a high-powered offense, so I am just trying to get down all of the plays."
During his two years of high school, Bagley caught 59 passes for 998 yards and 13 touchdowns. He was a late addition to the recruiting class, committing the week before signing day.
During his signing day news conference, Petrino questioned why he wasn't more highly recruited but was "very glad" to be able to snag Bagley at the last minute.
Now, Bagley wants to try and improve enough to get on the field this season. Even with a deep wide receiver crop, Bagley said he "hopes" to be able to see the field this season.
"I hope," he said. "I just have to put in work every day."
