Now maybe I'm reading your post wrong but let me see if I have this right.
Nash comes to Boston and see's his point totals go down but Lucic would go to Columbus and have his point totals sky rocket?
Rick Nash takes more shots because he has to. Who else on that team is going to score? Outside of his rookie season Rick Nash is the only Blue Jacket in franchise history to score 30 goals. Only Geoff Sanderson has scored 30 goals in a Blue Jacket jersey. Outside of Nash, Columbus is lucky if they get a few guys to score 20+ goals a season. You need to score to win and Rick Nash is the ONLY scoring threat on Columbus.
