That isn't really relevant as each draft has a different makeup. If this was a draft with an obvious number 2 (or a toss-up between 1 and 2), then it would be a different story. Nevertheless, the last 20 years its:
Malkin vs. Wheeler+Schneider
Ryan vs. Price+Matt Pelech
Jordan Staal vs. Kessel+Leland Irving
JVR vs. Alzner+Perron
Doughty vs. L. Schenn+Ennis
Hedman vs. B. Schenn+Palmieri
Seguin vs. Niederreiter+Kuznetsov
Landeskog vs. R. Strome+Danault
Murray vs. Rielly+B. Gaunce
Barkov vs. E. Lindholm+S. Theodore
Reinhart vs. Dal Colle+Scherbak
Eichel vs. Hanifin+Juulsen
Laine vs. Juolevi+T. Thompson
Nolan Patrick vs. Elias Pettersson+Oettinger
Svechnikov vs. Hayton+Bernard-Docker
Kakko vs. Turcotte+Pelletier
Byfield vs. Sanderson+Neighbors
Berniers vs. Kent Johnson+Lambos
Nemec vs. Gauthier+Mesar
Carlsson vs. Reinbacher+Musty
That's not even close to 8 out of 10. It depends on preferences, but its close to a 3rd with 2OA being better, a 3rd with 5+26OA being better and a 3rd being too soon or a toss-up/personal preference.
