Aside from the idealism, Cleveland Berto’s character sounds like he could eventually be a good fit in the Intelligence dynamic.
The cops of the unit wouldn’t be able to do their jobs if they weren’t intelligent, if not necessarily all scholarly.
Halstead does enough chasing and jumping (not to mention bouncing back from getting shot) that he at least qualifies as an athlete, and none of them are exactly out of shape.
I definitely wouldn’t qualify any of them a “family man” (or woman) with how seriously they take their careers, although Atwater probably comes closest with his brother and sister.
