Boston.com is not the Globe.
I mostly agree with the article; the list of players who accomplished what Seguin did at such a young age is minuscule and has a lot of great players on it. Him blossoming was their best chance to both win now and to bridge the gap to a post-Chara team. As for the off-ice stuff, players mature and it obviously wasn't so bad that they couldn't sign him to a 6-year extension (which actually made him more valuable as he's going to be underpaid for a while).
Of course, my opinion hasn't much changed since a day or two after the trade, and nothing new has really occurred to change things. Maybe when Morrow and Fraser come up the balance will change and we can have this argument again, but right now there's not much reason to write the article other than clickbait. That said, it is good to see at least someone in Boston with a mainstream media outlet not parrot the party line on the deal.
