you don't need a star captain rental. You need to make your own captains stronger and they learn by doing. By taking responsibility. Michael Jordan didn't learn to win with the help of Magic Johnson in the same thing. Learning to win is a process and as I wrote in 2020, it takes something like 4 years meaning that the team could be ready to win the cup in the '23-'24 season. It was just too early last year because the team had zero playoff experience. They had to learn and by acquiring some weak rentals who would vanish completely after the season you not only screw up the chemistry but also give an opportunity to some other players to hide behind the back of that "star captain rental". It was a lunatic move back then and still is. One of the most stupid trades ever.
that's your opinion. i don't need to remind you that you're a poster on an internet forum with no qualifications or experience so i know you'll understand that i (and most sane individuals) will defer to people like zito and his large staff of advisors who've worked with NHL players for decades and have a real understanding of the psychology of professional athletes and teams.
not that we can't speculate or criticize but your closing two sentences are, to be frank, ridiculous.
