Calling Sam Houston a Big Drunk is hardly smearing him, it's simple truth. You don't have to be a silly assed choir boy to be a great general.

Grant sure as heck wasn't a choirboy, for just one example.
"Grant is a drunkard," asserted powerful and influential politicians to the president at the White House time after time; "he is not himself half the time; he can't be relied upon, and it is a shame to have such a man in command of an army."
"So Grant gets drunk, does he?" queried Lincoln, addresing himself to one of the particularly active detractors of the soldier, who, at that period, was inflicting heavy damage upon the Confederates.
"Yes, he does, and I can prove it," was the reply.
"Well," returned Lincoln, with the faintest suspicion of a twinkle in his eye, "you needn't waste your time getting proof; you just find out, to oblige me, what brand of whiskey Grant drinks, because I want to send a barrel of it to each one of my generals."
That ended the crusade against Grant, so far as the question of drinking was concerned.
