Note: I am copying some information from another poster.
Steen played at Alabama, more than held his own against some of the best college def. He worked his way from an UDFA to 2nd team center passing Douglas to start versus the Falcons on Thursday.
He actually spent all of 2014 on the Arizona practice squad. He spent a couple of weeks on the Arizona practice squad in 2015 before being signed to our practice squad. I really should have known more about this guy.
If he does as well as I expect versus the Falcons, then I would be comfortable with him as the opening day starter.
