Certainly a few interesting names in the Blues squad this season! I'm not sure whether Sir JK is a genius or is completely mad - I'm sure we will find out soon enough!
Props: As others have mentioned having McCartney as the first choice LH is.....ummm..... interesting. He has never really looked that comfortable at prop, so it will be interesting to see how he goes. Faumuina is quality, Tu'ungafasi has incredible potential, and Ta'avao showed some talented during the ITM Cup - unfortunately all three are better on the TH side than the LH side. I'm not sure about the inclusion of Perry - he was ok for Tasman, but I didn't think he was a standout.
Hookers: I'm not sure what the reason for having 3 hookers when McCartney is also included. MacDonald is a quality player, but probably won't see much game-time behind Mealamu, while Parsons may be lucky to get on the field this season (unless there are a few injuries).
Locks: Some good quality here, and great to see Boric's name. Moli is starting to develop into the quality lock that was promised a couple of seasons ago, while I've got a lot of time for Cullum Retallick too (I was disappointed how little the Highlanders used him last season). Ali Williams may be past it in terms of AB selection, but can still do a job at this level IMO. There is plenty of good lock cover too, with Raaymakers, Luatua, and even Barrett comfortable at lock.
Loosies: I'm a bit confused about the makeup of the loose-forwards. Kirwan obviously favours a lock/6 on the blindside, and had plenty to choose from with Luatua, Barrett, and Raaymakers (Luatua should have this spot nailed down unless he gets injured though). I'm not convinced with the depth at 8 though - Saili is the only genuine 8 and has never established himself as a starting 8 at this level. Luke Braid is probably the best 8 in the squad, but is also the best 7, so will likely start there. I'm assuming Kane Barrett may have to cover 8 - I'm not sure whether he is capable of this as he has been consistently injured for the last two years!
I'm surprised there is no room for one of Dan Braid, Pryor, or Polwart - especially as the player effectively replacing them (O'Connor) has struggled to break into the Canterbury ITM Cup side. I do quite like O'Connor (or did when he was in the under 20's a few years ago, as that was about the last time I saw him play!), but I'm just surprised he has leap-frogged so many players who are actually playing (quality) rugby!
Halfbacks: Gibson-Park is a good addition, but he probably won't get much gametime behind Weepu and Hall.
First-fives: As expected.
Midfield: Good to see Fekitoa get a contract, as he had a very good season for Auckland. I see him competing with Willison for the starting 13 jersey outside of Saili. Willison is a good pickup - I think he has been under-used by the Chiefs in recent seasons. I'm not convinced about Moala being listed as a centre - he is a big strong lad who can play centre, but he is far more of a finisher than a creator.
Outside backs: Plenty of talented here, but there were certainly plenty of options. I'm not quite convinced about Halai - he is good, but I'm not sure he is better than the likes of Lam, Stowers, Bakers etc. I don't mind the selection of McKenzie, as he has some serious talent, and could be a top class player in future. However I do agree that someone like Kurt Baker would have been a better option purely in terms of who is currently the better player (indeed I would have found room for Baker in almost any NZ squad). I agree with a number of others that Ben Lam was very unlucky to miss out. I'm somewhat surprised that Nick doesn't rate him higher, as I thought he was one of the most (if not the most) dangerous wings in the entire ITM Cup. He has some serious pace and power - he completely destroyed Otago when we played Auckland down in Dunedin. I'm not convinced 100% by him yet as he still make a few too many basic errors and tends to drift in and out of the game, but he certainly has the raw tools to excel at Super Rugby level.
