I could have sworn that Leigh were in SL last season and Fev just needed to beat Toulouse on their own patch to secure a SL spot.
On a related issue, their game on Monday (Fev v Leigh) is going to be one of the most important games of the season.
It's hard to see too far beyond those two for the promotion spot.

It's early day yet, but those two would seem to be the safe bets. I expect both teams to lose games though and come the MPG, home advantage could play a major part, so consistency throughout the season will be key
Fev will play basic 5 + a kick big Mac rugby ....Leigh might be slightly less direct....2 contrasting styles and as I say, bot will lose to "other sides" this year.
