The best bigs I’ve had on my championship caliber D2 FB/press teams run the gamut between the two examples above (actually a little better generally, because I was assuming you were talking about D3). That’s why I don’t like thinking in terms of prototypes, you start putting players in boxes, and get too caught up in what they don’t do, instead of what they can do. Obviously, you want to try to get the best players *in your system* available to you. It might help to use the advanced weighted rating system, though I’ve never really liked them and don’t use them myself. In general, FB/press utilizes speed at all positions a little more. It’s still least important at C, as with every type. But for FB/press, it’s a little more valuable, so I would weight it a little higher than I would do for other set combos. Does that make sense?
Another thing I forgot to mention, FT shooting is more important for FB/press as well, because if you’re doing it right, you have more opportunities from the line.
