I was a kid in North Chicago suburbs, and have lived in St. Louis, San Antonio, and Houston.

First Chicago - Cubs, White Sox, Bears, Blackhawks,  Bulls  and I think there's an MLS soccer team, and a spattering of satellite minor league baseball teams in the area. All are well supported and have a national presence.  ( oh, yeah, Chicago has real, barehand softball too ) -- Great Sports Town ?

 St Louis - Cardinals, Rams, Blues.  My opinion is St. Louis as a baseball town.  The Rams and Blues get planty of fan support, but it's the year long  love affair with the Redbirds that sets it apart.

 San Antonio - Spurs bay-bee.  Spurs own San Antonio. No questions asked.

Houston -- Astros ( I think there's an MLB team here ), Rockets, Texans, MLS Dynamo.  This is a football town.

What I think are great areas for their sports franchises --

Boston / New England area --- Celtics, Bruins, Red Sox, Patriots.  If there's a winning reputations, seemingly always in contention,  and rabid fan base, this is right up there.

New York - 'nuf said.  the only question that  remains is Jets or Giants.  Chicago North Side / South Side, Cubs/ Sox, I understand.  Jets / Giants someone will have to educate me.

Denver - Broncos, Rockies, Nuggets, Avalanche.  Always heard Denver is a great sports town.   Broncos have plenty of history, and the Rockies have a good draw.  Maybe it's the Colorado demographics and geopgraphy that propagate the great sports town rep.

Bay Area - Giants, 49'ers, Raiders.  Sacramento Kings are close but I've heard there are facility issues, but sports town ? Should be. Lots of winners and great history.

Pittsburgh - this might be it.  Steelers, resurgent Pirates, and Penguins.  Just off the top of my head, the Steelers own Pittsburgh. Cool that all three teams have the same colors.

 Detroit -- Tigers, Red Wings, Pistons. wow. back in the day Detroit kicked butt.  It probabaly was a great sports town.  All those teams rocked, and contended, and won.

Dallas - Rangers, Cowboys, Mavericks, North Stars. Great Sports Town ?? not so much. 

Who's on your list ---  Great Sports Towns, good sports towns. My jist is metropolitan areas.  Lincoln, Nebraska great in the fall, but a one horse town.  Who's on your list.....hometown bias is accepted at this window. 

overall - ??

Have at it.......
