While 11 in-a-row is impressive, it can also set you up for failure. We all saw what happened to the Roosters last year, they got beaten at the wrong end of the season and couldn't regroup. A lot of these Sharks wins could have easily been losses and it's just been a few trick plays going their way at crucial moments that have proved the difference.
They've got a couple of boneheads in their side as well. Fifita, Tagataese, Ennis, Townsend, Leutele, Feki, Barba, Prior, Paulo, Graham etc. all have mistakes in their game and holes that can be exploited in the bigger games.
They're riding a wave of momentum and for their long suffering fans, I'm happy for them. However, nobody in the Top 4 convinces me at the moment. I still think there's room for an outsider to come along, jag 4th spot and steal it from there.
