I'm not so much building around tactics, but if I know I'd like to play a certain way, why not get players that fit?
I look more for size and skillset than anything else; all skills being the same, a bigger guard has more value to me than a smaller guard. If I have guy that's a 6' 10" forward who can guard the perimeter and defend in the paint, that guy is a weapon. If I can play him with a similar sized guard who can defend the perimeter and the paint, even better. Skillset determines the best position fit for me, then size. I don't know if you looked at the link i shared, but in that game my small forward for that season was a 7 foot point guard. His skills determined where I deployed him.
Even if it never happens in this league, Joy Beko, my 6' 10" power forward, has actually run point guard for me numerous times. His assist to turnover ratio this season is actually one of his worst since I acquired him. I've long used big point guards at small forward, but I've also had some that were strictly point guards. If I have a guy that can only play one position, he better be REALLY good at that position or have a really special skill that makes him valuable. Being versatile lends itself to a press, IMO.
