The answer is that Walsh is a troll who loves cancer. He's also associated with Kimmage, as they are from the same country. LA disclaimer: all the other Irish are wonderful people.
What you have to understand is that LA's Cofidis story fits in with the narrative of the fable. Who gives a $hit whether it's true or not? Half of what he says is a lie so he might as well take it all the way. He can create them a lot faster than you can debunk them. He understands that 9 casual fans overrule 1 person who may dig a little below the surface. Then you have the willfully blind fanboys who'd love to give the guy a sensual massage with the requisite happy ending. How you gonna fight those kinds of odds? Then to gild the lilly you're a jealous and angry hater. If he's successful painting LeMond with that brush, how in the hell is the fairly informed cycling fan going to stand a chance?
The above answer satisfies well above 90% with fanboy proclivities. This armstrong is going to be an amazing politician.
BTW, right now he's playing with the kids in Austin, training in Aspen, preparing for the newborn, fighting cancer, wind tunnel testing, core training, building soap box derby cars, sewing dresses with the twins, coordinating parenting with his ex wife but good friend Kristen, using hundreds of thousands of gallons of water because it evaporates quickly in the Texas heat, badmouthing then praising Contador, hanging out in art gallleries, taking half hour showers, hobnobbing with politicos and picking up skeezers in South Beach/Hollywood/Tribeca with Bill Clinton.
In addition to being 7 time TdF champion, the guy has created the 36 hour day. I wonder if he'd date me?
