I'm guessing you're playing small buy-in tourneys like me. I usually play $2-$4. And at least on Stars where those get thousands of players, there are surely going to be anomalies. Sometimes these are donks who got lucky, and sometimes they are the good players who were lucky enough to be able to pick off some donks by getting top hands early.
For example, a couple nights ago in the CC invasion, $2 90-player SNG, on like the 3rd hand some guy opened from utg with an all-in. I had aces, and called. The original raiser had already dropped 500 chips in one of the first two hands, so when another player called on the button, we both had about 500 chips left. Flop came, I put in the rest of the chips and the button called again. Original raiser had QTo, button had AQo, and I was on my way to a second place finish.
Sometimes, if you're the good player, you will be the lucky beneficiary of the early donks. Most times you won't but you've got plenty of time to make it up by playing good poker.
