Adam Johnson's strengths and shortcomings are no secret.
Johnson, of course, is a strong skater. He's the fastest prospect in the system. He's a playmaker and a goal scorer. He's a versatile forward who is comfortable at both center and wing.
Johnson's weakness, well ... is his weakness.
When the Penguins signed Johnson out of development camp in 2017, following his sophomore season at Minnesota-Duluth, he was 6-feet, 175 pounds. He had the height, but he needed to fill out his frame. Now, in his second-year pro, Johnson is still working on achieving that goal.
