If Ferrari had just held it together for a couple more races it would have been an epic finish to the season. Sadly they peaked early and lost momentum while Mercedes finished strong. Also I forgot that this was the first year for the halo, things should be interesting.
As for Rossi coming to F1, I wouldn't bother if I was him unless one of the big three offered me a seat. In Indy he has a shot to be competitive where as in F1 if you aren't driving for Mercedes, Ferrari, or Redbull you are just trying to dethrone Sahara Force India as the best little team in the league.
