Famous quotes containing the words national, basketball and/or league:
“The national distrust of the contemplative temperament arises less from an innate Philistinism than from a suspicion of anything that cannot be counted, stuffed, framed or mounted over the fireplace in the den.”
—Lewis H. Lapham (b. 1935)
“Perhaps basketball and poetry have just a few things in common, but the most important is the possibility of transcendence. The opposite is labor. In writing, every writer knows when he or she is laboring to achieve an effect. You want to get from here to there, but find yourself willing it, forcing it. The equivalent in basketball is aiming your shot, a kind of strained and usually ineffective purposefulness. What you want is to be in some kind of flow, each next moment a discovery.”
—Stephen Dunn (b. 1939)
“We’re the victims of a disease called social prejudice, my child. These dear ladies of the law and order league are scouring out the dregs of the town. C’mon be a glorified wreck like me.”
—Dudley Nichols (1895–1960)
