If you're a normal player that doesn't game the draw system, you're not going to be scoring 5 goals every match.

I generally look for a distribution of 50/35/15 for ST/MC/DF. The people with obscene 1.5+gpm averages are usually a part of incredibly strong teams or are rebuilt around them every season. Granted, there are exceptions, (Costa comes to mind), but generally 0.5 gpm is decent and anything above 1 is exceptional.

you could always try training a high def high physical striker for a lone pressing poacher hat never goes offside?
