Jay, yes I do agree, but I think part of that lack of interior defence comes from lack of quality bigs.
I guess I should qualify that from my point of view. When we had Boyd and Sporn, things were dandy, and we dominated. Boyd went OS and Sporn's knees started playing up. We just could not attract any real quality bigs to the team, with Brogan coming back to play a prt time role, and well, lets face it, she was past her best days (still played a serviceable game though). Braithwaite has been good for the team, but did suffer against a lot of the other centres. Summerton has been a shining light, and if Sporn had been able to stay for a couple more years, could have fostered yet another Boyd/Sporn like combination.
I dont want to take away from anything the current or past Lightning players have done...the fact they havent missed a play off since they entered the league is no small feat, just one more big would do them wonders I feel.
It's purely my 2 cents...but...I'm not a coach.,.and there's obviously some very good reasons for that :)
