But Shaheen will get a fair shot under new Bears tight ends coach Clancy Barone, who held the same position with the Vikings back in 2017 when Shaheen was a draft prospect out of Division-II Ashland University.
Barone saw great potential in Shaheen then and is willing to see what he has to offer in 2020.
"Here's a guy I absolutely loved when he was in college," Barone said recently. "I thought a fantastic prospect. I remember talking with (former Bears coach) John Fox about him and Foxy said, 'He looks exactly how tight ends should look.' And he's right. I mean, the guy is physical. Everything about him, his height, his length, everything about the guy is what you want. For whatever reason did he have a hiccup here or there, injuries, whatever else?
"He's a guy who has a very bright future still. I would not say any more than just Adam is a guy I think has a very very bright future, and I've got plans for him to do things in our offense."
Before the 25-year-old Shaheen can fill a role in a game, he must first earn place on the Bears' roster. The Bears added at the Y tight end position this offseason by drafting Cole Kmet out of Notre Dame in the second round and by signing veteran Demetrius Harris.
Shaheen played in just eight games in 2019 before he was a healthy inactive for the Bears' contest against the Lions on Nov. 10. He was later ruled to have a foot injury and didn't return for the rest of the season.
The 6-foot-6 Shaheen has 26 career receptions and four touchdowns in 27 games. He's entering the final year of his rookie contract as one of nine tight ends on the Bears' roster.
