Leinster look to be coming into very good form. You can say they beat an average Castres side but European form is different to domestic form. Look at Munster down the years, or Dortmund in the champions league this season, topping their group yet 17th in a relegation battle in the Bundesliga. Leinster should've walloped a poor Quins side before Christmas, beating a team no matter how poor still requires execution and guile and they had that in abundance like the Leinster of old. This is precisely where they want their form to be heating up, lets see how Wasps next we goes first though.
Munster had a poor game and Sarries feed on that. Munster were a level below this tournament, Sarries at Thomond aside they were poor every game. Next season I'm sure it'll be different with the coaching more bedded in. Shame JJ has left, a player like that is a light of hope in a dark season as you can look to them to raise the team. Munster have let their X Factor and 2012 Junior RWC player of the year runner up leave.
Ulster have been awful too, shipping 60 points theres no way to disguise how awful Ulster are currently. An Irish team on a bad day should be shipping no more than 30 no matter who they're playing. Ulster admittedly had a weakened side, no motivation etc but hell they're a proud province that will hurt them.
Its not all doom and gloom things just didn't go the way of Ulster and Munster this year, if they manage to qualify for next years tournament, I'm sure it'll be a different story altogether. But on a final note, how much more tempting is it to buy an import for a team? I can't see an Irish or English team doing this yet as of their management, but the urge to buy a player to is ever stronger due to the higher competition. Things might get a bit crazy the next few years I fear.
