You're definitely right that sales teams are motivated by commission. What we've come to find out, both working in these teams and managing them, is that the most powerful drivers still are intrinsic. Recognition, camaraderie, purpose, being a part of something bigger than oneself...
I think sales teams get a bad reputation because of the lone-wolves, most people working these types of jobs might be more "alpha" than others but still want to feel like they are making an actual impact in something, even if it's just getting their team a "W" for the week.
