[2][4] That year, Kallman scored her first collegiate goal against in-state rival the Florida Gators in the 89th minute to send that game into overtime.

She followed that up as a sophomore by playing every minute of all 26 games for Florida State while helping the Seminoles to their first ACC Championship and fifth NCAA College Cup appearance.

As most of Kallman's collegiate and U-20 international experience was spent in the central defense, she was largely expected to step into the hole in that position left by Lauren Sesselmann's departure for the Houston Dash through the 2014 NWSL Expansion Draft.

However, through the first few games of the 2014 NWSL season, she featured as the left wing-back, providing width in the attack for FC Kansas City's possession-oriented style.

Kallman adjusted to the role well, particularly against the high-powered attacks of the Portland Thorns and Seattle Reign during the playoffs, helping the Blues win the 2014 NWSL Championship.
