This is simply not true. If you think he has not developed since 2017, or even regressed, I don't know what to say. 2020 Lias Andersson is a better player than 2017 Lias Andersson. That's not my opinion, that's fact. Look at his performance this year compared to his D+1 year and it's quite obvious.
I am not suggesting Lias is better than Barron. All I am saying is that they are the same age and that their different paths have led to different expectations. Lias played in the NHL at age 19 and 20, while Barron was still in college. Of course Barron has been trending upwards. That's what you expect in college. Lias hasn't been good in the NHL But he has still developed as a player. I don't think he will ever make the team for us after what happened but fact is that he and Barron are the same age and there's a possibility they play together in Hartford next season. That will be the first time we can actually compare them.
