If a basketball fan/player wanted to visit the basketball hall of fame and then saw that MGM had a hotel tower a couple blocks away with a casino, then that becomes a nice weekend trip. A squat dowtown hotel isn't an attraction
In a more "serious" (read: snobbier) world, the Springfield Armory would well outdraw the NBA Hall of Fame, as awesome and fun as it is to gaze at Bob Lanier's size 22 shoes.
After all the Armory was quite literally consecrated by George Washington. The industrial supremacy that it created from 1790-1860 exemplified the superiority of the North's socioeconomic lifestyle and cultural values to the South's slaveocracy. Later of course, it created the M1 Garand rifle--aka the "Saving Private Ryan" rifle.
So you could say that the Springfield Armory, in a sense, "saved civilization" twice, from 1860-65 and again from 1940-45.
At a more prosaic level, Springfield's ongoing woes have never been a mystery: at the macrolevel, it remains tethered to the stagnant Connecticut River valley economy that extends south to Hartford.
At the micro level, the construction of the I-91 through downtown--the way it amputated the waterfront from the rest of downtown--remains of course an unmitigated debacle, the wiki entry for which is worth quoting in full (apologies for copping whighlander's act; I promise not to do it for a long while hence):
"hasty, poor urban planning decisions during 1958 created the now elevated I-91 viaduct along the Connecticut River, which essentially cut off Springfield from the Connecticut, the parks surrounding it, and the Basketball Hall of Fame complex, preventing foot traffic and resulting in untold losses of tourist dollars among other losses....
.... Recent academic papers have documented negative economic and sociological effects of I-91's placement in Springfield – it has fragmented three neighborhoods, inhibited the economic growth of Springfield's most valuable land – on the Riverfront and around the Basketball Hall of Fame – and essentially made the river inaccessible to people as a place for recreation and tourism. Recent city planning polls rate Springfield's I-91 among the worst urban planning decisions made by an American city. The highway's inhibiting effects on riverfront development were exacerbated during the 1980s and 1990s, when giant, above-grade highway parking lots were built underneath I-91, and later when earthen, grassy mounds and 20-foot limestone walls were constructed around large sections of it, blocking all but the tallest Metro Center buildings' views of the Connecticut River, and discouraging economic and social interaction between Metro Center and the Basketball Hall of Fame."
