Sack made a bold move on Thursday to acquire 2 young CB's.
Vontae Davis and Joe Haden will join the secondary and will team up with Ike Taylor, Troy Polamalu, and Ryan Clark.
The price was steep as the Steelers lost Lamarr Woodley and Ben Roethlisberger.
The offense will now be in the hands of Colt McCoy.
"We wanted to get younger and deeper in the secondary and we did that" said Sack.
