I'm more a fan of increasing the overall power/strength/size/speed of the team than having too many forwards that are all about the big minutes,with numbers that look good on paper but really lack quality impact that can fatigue and hurt the defensive line.
Yes it is a fine line, you can go too far the other way and have a pack of YouTube,highlight reel, lacking consistent substance types who can go soft really quickly when the game flow is against them.
The Doggies have the wrong type of size, lethargic flat wicket types along with too many over-rated clubman who lack spark. Combine that with halves who don't have structured ballplaying ability and you create a predictable stuttering mess that only looks good during fresh moments or on the few occasions the forwards get a role.
I'm not a big fan of Aaron Woods, more an over-rated media favourite but i do admit he can have his good moments----i don't watch as many games as the past so more going off past impressions from the limited times i have watched a Tigers game.
Teams that have improved the overall size, speed, strength, power of their squads that can keep coming at you tend to improve more than retaining a club full of clubman and previous gen size types.
Roosters,Souths,Nth Qld have shown what harnessed structured power can do to a squad, winning premierships and you can see a few other teams have improved in this area also in recent times for good results.
Manly is on the right path, i would like two more forwards for depth as we have already seen with injuries and suspension against Souths that when the tide is against us we can crumble. In saying that a little experienced leadership that day after the good start should of resulted in a win, so not entirely down to a lack of size on the day but it didn't help.
