The versatile 19-year old USA youth international made his first team debut for the Brum in the League Cup back in August and has since made three appearances in the Championship.
Packwood is being touted as a future USA national team star but at the moment he is simply happy to gain education in different aspects of the game at St Andrew's.
"Pretty much everyone here agrees my best position will be center back," he told MLSsoccer.com.
"Having experience in midfield, I'm comfortable on the ball. And I have the size and physique to be a difficult defender to get past.
"It's a steep learning curve. It's a difficult league, even for established players. I'm getting used to it as time goes and I play more games."
And Packwood indicated that he certainly has high hopes for Birmingham who currently sit 19th in the 24-team tier two competition.
"Our goal is to win promotion to the Premier League," added Packwood. "We want to be in the playoffs, or even pushing for [automatic] promotion."
