Looking at the two teams named I'm finding it very hard to pick a winner!
I think the Crusaders have the edge in the front-row due to their world class propping rotation (even if their best prop is on the bench). I've got a lot of time for McCartney, but he is better at hooker, and while Faumuina is a good ball running prop, he still has work to do at scrum time.The blues do have a clear edge at hooker, but this is not enough to overcome the Crusaders edge in the props in my opinion. Despite having the edge in the front-row I don't actually think the Crusaders will have much (if any) edge at scrum-time, as they really lack a tight-head lock (they will REALLY miss Brad Thorn here), while the Blues have a strong scrummaging tight-head lock in Boric, and Ali Williams is not bad at scrum-time either (probably better than either Donnelly or Whitelock in any case). I think the Blues have a slight edge in the locks, but only just.
Both teams seem to have pretty well balanced loose-forward trios, though I do think the Crusaders lack someone who can run the ball effectively close to the breakdown (ala Kaino). Read does a good job running a bit wider, but I think the Crusaders will have to rely heavily on there props to get them the go-forward ball they require (this is another major area where they will miss Thorn). It will be interesting to see how Kaino goes at 8 - he will need to have a strong match, as I see the Crusaders having a very slight edge in the loose-forward department.
The halves look evenly matched to me - Mathewson and Hobbs are the better ball runners, but Ellis and Bleyendaal play the tactical game better. Likewise the mid-field looks pretty evenly matched - there could be some big collisions between Fruean and Ranger! Some interesting matchups out wide too: I think Raikuna may have trouble containing Dagg, but Raikuna himself could cause some damage if he gets a bit of room to move.
In conclusion I have no idea who is going to win - I'm going to pick the Blues by 5, solely because they have the home advantage...
