My opinion would be to pass on the buck you mention,at 70 inches in your part of the country he is 1 1/2 years old or at the very oldest 2 1/2 years old.This next year he should have significant antler growth,perhaps enough to get his beam or tines further out away from his face.There also is the possibility of him not repeating the antler configuration he has now.
I appreciate your concern for your teams score but I don't believe that should be your consideration as to which buck you kill.If you want to shoot this buck and you will be pleased with it then take it if you have the opportunity,if not don't.
