Importance of Stack Sizes- is it #1 factor?

I am not recollecting what pro wrote this but thought it would be cool to post it and get your reactions.

Do you agree or disagree?

Stack Sizes- you should still take flops with people, because they will play really badly and make huge mistakes post-flop, but you have to be conscious of your stack size and what it allows. Everything — and I mean f---ing everything — in tournaments is dependant on stack size; it is clearly the most important concept
