ALAMEDA, Calif. -- Was it not just a year ago that the Oakland Raiders were seen as returning one of the best, most physically intimidating offensive lines in the NFL?
A unit with three Pro Bowlers in left tackle Donald Penn, left guard Kelechi Osemele, who was also named All Pro, and center Rodney Hudson with a rising star in right guard Gabe Jackson had added capable right tackle Marshall Newhouse in free agency and reinforcements in the 2017 draft in David Sharpe and Jylan Ware.
