In on specific order: Hasek, Jagr, Crosby and Ovi.
The fifth spot is between some of the long ago players like Beliveau and Richard, which I generally leave up others as I'm really only going on stats and stories unlike "modern" players I've actually seen play.
Ask again when he's retired (or close to it) and Connor almost certainly will force me to drop one of the above outside the top 10.
