I think that you are stat-line scouting. Butler has spent the majority of his MLB career as a contact-oriented slap hitter; which is why he ranks near the top in BA, BABIP, LD%, K%, etc. among qualified DH and near the bottom in ISO, Pull%, etc.
I guess that it is possible that Tellez turns into Butler; but he hasn't really shown anything to suggest that he's going to come up and turn into a 6'4 240+ pound hitter who sprays line drives all over the field. Billy Butler is a career .320 BABIP hitter despite the fact that he possesses zero athleticism.
