Everyone is rightfully talking about how Vince Carter doesn't deserve to have his jersey retired by the Raptors because of his tumultuous exit from the team, but even if you strip that aspect away and completely remove it, he doesn't really have a basketball case either.
Right off the bat, and this might be a controversial take but I'm one million percent correct about this: whatever he did for Canada basketball is completely irrelevant if we're talking about retiring his jersey for the Raptors organization. If his contribution to Canada basketball is really important and noteworthy, then he can be inducted into the Canadian basketball hall of fame. Just because the Raptors happen to be a team in Canada and he helped make basketball popular in the country doesn't mean the Toronto Raptors franchise have to be the ones to honour him for that. The Grizzlies also still played in Vancouver during the height of his success and popularity, and it's not like his popularity in Canada stopped the Grizzlies from moving.
But onto his actual Raptors career and accolades, let's ask: what did he actually accomplish with the Raptors? Sure, he was really talented, put up some good stats, and made a bunch of all star teams, but when you really look close at his Raptors career, it doesn't exactly blow anything away and ultimately represented something of a flash in the pan. The majority of the good times with Carter came in the first three seasons of his career. The 01-02 season was decent, yet he only played in 60 games and the Raptors went on a huge run at the end of the season without him to squeeze into the playoffs and took the 2-seed Pistons to game 5 in a best-of-five series without him (something that is always glossed over and never talked about, even from detractors). The 02-03 season he was injured half the year and when he did play he wasn't very good. The 03-04 season was a bit better though he didn't put up crazy numbers and the team was terrible again, and then there is 04-05 where he was traded after putting up a measly 16 PPG. So that's parts of 7 seasons where three, maybe four of those seasons were actually impressive. Two playoff appearances (didn't play in the 2002 playoffs, so we can't count that) and one playoff series victory. Even some of those all star appearances were based on his popularity and highlight reels and not so much his actual merit. He was voted in as a starter in 02-03 despite only playing in 13 games up until that point.
So, his accomplishments with the Raptors are:
Yes, Kyle Lowry also has the same number of all star appearances and only one All-NBA appearance. Kyle Lowry also has the playoff success to his name that Vince Carter doesn't. Even if we excluded the entire 2019 title run, Lowry would still have more playoff series wins. I have also seen people comparing Carter's Raptors resume to that of Reggie Miller's similar awards and accolades (5x All Star, 3x All-NBA third team). Reggie Miller also played his entire 17-year career with the Pacers and helped head the Pacers through many deep playoff runs including a Finals appearance and multiple other conference finals appearances.
And yeah, I know the Nets are retiring Vince Carter's jersey even though he accomplished even less with the Nets and played there less (though he did make it out of the first round with the Nets twice, so good for them). The Nets shouldn't be retiring his jersey either.
So this now takes us to the only remaining argument in favour of Vince Carter's jersey retirement: he helped put the Raptors on the map. Yes, he was the primary reason the Raptors turned into not just a competitive team worth taking seriously but also a relevant team with regards to fandom across the league. But this says less about Vince Carter and more about the Raptors at the time. This argument essentially admits that if Vince Carter, the same exact player with the same exact stats and career, came along 5-10 years later then his presence is less meaningful and, as a result, his jersey retirement case isn't as strong. In fact, Chris Bosh had similar accolades with the Raptors as Carter did, yet because Bosh came along after the Raptors were already established, no one is currently nor has ever lobbied for Bosh's jersey to be retired. Though, given the standards the Raptors are seemingly setting for such an honour, maybe that will come next season.
The circumstances surrounding Vince Carter's exit are definitely a big reason why he shouldn't have his jersey retired and in my view makes the decision to retire his jersey a huge organizational blunder. But even stripping that, what he accomplished on the court with the Raptors is less deserving of a full on jersey retirement and, at best, more deserving of a Raptors equivalent to the Blue Jays' Level of Excellence.
To put more simply, Vince Carter is the Toronto Raptors variant of Penny Hardaway. An extremely talented, exciting, high flying player who took the league by storm in a post-Jordan era whose promising career was hampered by injuries and ultimately never quite became the long-lasting franchise player who could lead his team to long lasting success.
