We have Backes, Acciari, Kuraly for that from a physical standpoint and Bergeron, Marchand, Pasta and Heinen for that in a more creative way as well. Heinen was 5th on the team in takeaways (behind those 3 and Chara) and had almost 2x as many as Wood.
As far as the affect on Ovechkin, pretty sure the correct answer here is neither.
I think people just want that old style hockey back and have it through the lineup more so than we already have. But the cost for that shouldn't ever be a player that generates more offense and more turnovers.
