Well the truth is the squat is a quad dominant movement (yes, there are the low bar squats etc but I've rarely seen athletes do low bar squats, personally at least).
In a sprint, which is a horizontal movement to begin with, the hamstrings and glutes play a much more important role. Then there's the structure thing. A guy made for sprinting isn't necessarily made for squatting. There's a bunch of stuff going on.
But the thing is - anything that you do that gets you STRONGER, ANYWHERE, assuming you have the correct movement mechanics, no mobility issues and a good agonist/antagonist balance - is also going to make you faster. At least it shouldn't make you slower, if anything.
That's why you have periodization for athletes - different phases, different exercises and different EXPRESSIONS of power and strength. Ultimately you want the non-specific strength and power exercises to carryover to the specific power and reactive "stuff" that you do.
