But Connor, 20, found he had so much more to learn. Perhaps the most significant lesson was there is little time to relax as a professional hockey player.
"I'd say that on the ice, you have to prove yourself every day," Connor said after the conclusion of Jets development camp in June. "You have to come in every day, including practices, and you can't really take days off. It's definitely a full-time job.
"Off the ice, that was one of the biggest adjustments for me. Coming from college, I had so much time. Your day is kind of planned out at college. Now, you're at the rink three or four hours then you go home and it's … whatever. What you have to do is find the routine that works for you. About halfway through the year, I got to talking to some of the older guys to see what they do and learned from them. There is a lot more time and you have to manage it."
Connor, a first-round pick (No. 17) in the 2015 NHL Draft, led all NCAA players in his only season at Michigan with 71 points (35 goals, 36 assists) in 38 games in 2015-16. He began last season on the Jets roster but was sent to Manitoba of the American Hockey League after having four points (one goals, three assists) in 19 NHL games. He fared better in the AHL, with 44 points (25 goals, 19 assists) in 52 games.
Connor said he was in many ways a typical, wide-eyed NHL rookie who was forced to learn and adapt quickly.
