No worries Haboob... although I must say you'll never convince me that AFL hits are anywhere near as full-on as those in rugby or rugby league.
I'm a big advocate of 'sport specificity,' that is gearing your training to the sport that you play. Now if your 'sport' is to look good then all power to you, bulk hard and then cut up, it's quite a simple concept, though it takes a degree of dedication.
HOWEVER, for those of you looking to bulk up or get stronger to be better at your chosen sport things are not so simple. If you're mid-season bulking hard and fast will likely result in a subtle change in your biomechanics. (the way your body moves) Your frame isn't used to the sudden increase in weight, sport specific movements will seem somehow slower or not as efficient, you may find you lose some acceleration and agility and you may find you fatigue easier, particularly when it comes to endurance type exercises. ALSO there is a point at which your frame cannot efficiently support the mass it's carrying, even if you're at 6% BF. For everybody it's different and basically depends on your skeletal structure. In general, the larger the skeleton, the more mass you can effectively carry.
Case and point... I know my optimum playing weight is around 84kg. (I'm about 5'10'') At that weight (8% BF) I could bench 140kg, squat 160kg and run 100m in around 11 secs. I have also played rugby at 86kg (again 8% BF) The difference was amazing, I felt so sluggish on the field. I could bench 160kg and squat 180kg but my speed, acceleration, agility and endurance all suffered. And believe me, when you're up against a few All Blacks (if you know your rugby) you need to be on top of your game.
How many sports stars have tried to 'bulk up' to get a competitive edge only to drop out of contention because their game turned to total sh*t?
When it comes to competitive sport, bigger and stronger is not necessarily better. If that were the case every professional sports player would be gargantuan. In professional sport, skill and ability is most important.
