Leading up to training camp for the Pittsburgh Steelers at Saint Vincent College in Latrobe, there were some roster concerns, particularly at receiver and cornerback.
Quietly, there were also depth concerns at the outside linebacker position behind the trio of T.J. Watt, Alex Highsmith and Nick Herbig.
The Steelers claimed Jeremiah Moon from the Baltimore Ravens in January to give them some experience on defense and special teams. They also brought back practice squad guys David Perales and Kyron Johnson.
But depth was an issue then.
Two days into padded practices it appears to be a potentially serious issue now.
