Are there any stats on it?
I have no idea, I doubt it and I would treat any "good" claims as sales talk and nothing more.
My first questions to you would be where and who are your target markets?
Then how do you expect people to find the site, solely through the SERPs or by paid-for promotion or through the team's supporters / club / business?
Insofar as my experience is concerned, the last few years internationally has seen a consolidation of .com as the most preferred extension, nationally and noticeable an increase in country-specific domains such as .co.uk / .de / .fr
Some English language countries, such as India, can at times be totally dominated by .coms.
If your example.team is very speciifc rather than thisistheextremelylongnameforourteam.com and is a recognised "team", I assume sport here, in its own country / region, then it could be a good and viable option however do check out the registrar's T&Cs for that extension.
Apart from .com/net/org these days it is very difficult to rank an alternative extension internationally, not impossible but very, very difficult.
