Sure you can. Get a bunch of high contact, good eye, decent split guys and you'll do just fine, even if their Power #'s are in the 50's or 60's
Parriss Nichols Karl
are all good examples. Those are my 4 best offensive players w/Power numbers of 56, 69, 63 & 65. Get guys like that.
Once you get down into the low 40's (or worse) with power numbers then a guy needs to be a real high OPB guy or Gold Glover.
