I'm not agreeing or disagreeing with your overall point. But if you spend 13 or 14 million on your defense, it won't be as good as anybody's. You may feel that by alotting your cap money that way the forwards and goalies can pick up the slack, but to say that you can have an equally strong D is patently false.
Like I said, I probably won't get as many points as some.. probably most.. but I don't care about getting points from my defense. In this type of league, I want my defense to flood the peripheral categories. Blocked shots, hits, SHTOI, PIMs, and I even look for good +/- guys.. points are a bonus.
Personally, I'd rather have a Dmen who hits all the peripheral categories and gets 15-20 points making 2 million then a guy who has decent peripherals and gets 40-50 points making 5-7 million or more. But like I said, to each their own. Not saying my ways the best way but it's worked for me. I'd rather spend my cap on forwards, personally.
