Gettleman signed the ex-Jaguar Omameh, 28, to a three-year, $15 million contract with $5.5 million guaranteed. Omameh stands an imposing 6-foot-5, 322 pounds, but he is on his fourth team already entering year six (Tampa, Chicago, Jacksonville) and Jacksonville let him walk in free agency and upgraded at guard by outbidding the Giants for Carolina Panthers All-Pro Andrew Norwell. Omameh, like Solder, is a steady personality who is here not only to improve the line’s play but also to be a leader and positive off-field influence, particularly on Flowers, whose locker stall is now immediately adjacent to the veteran guard. Omameh hopefully will get a better push at the line of scrimmage beginning on Sunday, though, or the right side could really struggle. It’s worth noting, by the way, that O-line coach Hunter on Friday put the onus on the running backs, as well, when asked about his line’s run game struggles this preseason: “The most important element in the running game, first of all, is the runner, and then the runner has got to be in sync with the offensive line and the tight end, the people that are the blockers,” said Hunter, who is in his 35th year of coaching, both in college and the pros. “It’s all nine guys working together and so as they continue to establish, it has to be the line in sync with the back having a good feel.” Shurmur, by the way, said Thursday that all three backs that are dressed Sunday — Barkley, Gallman and Stewart — will get carries.
