Walter Report's Charlie Campbell likes what he's seen in Florida cornerback Marcus Roberson.
With size-challenged (but big on talent) CB Jason Verrett off the board just a pick earlier to Detroit, his mock draft has the Steelers taking Roberson with the 46th overall pick.
Roberson (6-0, 191) has upside to be man-cover corner with an nice combination of size and speed. I know some league sources who are high on Roberson. The Gators left him on man-coverage islands throughout his collegiate career, and he performed excellently, especially in 2012. Teams rarely tested Roberson as he blanketed his receivers.
It's as solid a bet as it gets; the Steelers are going to add a cornerback, very likely somewhere within the first three rounds. The Steelers don't have their third round pick, having traded it last year to Cleveland for the rights to take Shamarko Thomas - when safety was the position needing depth for the future. It's cornerback this year, and it wouldn't be a surprise to see the Steelers make a move if they have to for a cornerback they can get to contribute his rookie year and work into a starting role shortly after that.
Maybe Roberson is that player. He'd likely compete more realistically for playing time in Year 1 than Campbell's projected first round pick, Kelvin Benjamin, would, but it'd be a solid first two picks for a franchise that really needs to make a few scores in this draft.
