our nfl insider shea taylor and guys, mike ipati and evan mathis both out, how significant is this to the offensive line, jay? >> i think it's pretty significant because you are relying on these guys to help make your running game no. 1 in the league. david johnson did an excellent job starting run on the first snap from scrimmage. that's what you want to open thing up. how effective can these young guys be stepping in? they did play well in the 49ers game. now you'll go up with three weeks of front that will be tough. how do you prepare for that? how are they able to execute and stick with the same running scheme they've done? >> they call for earl watt who can slide in right there behind and jay, with ipati out, john wetzel who is usually a tackle slipped in as guard. bruce arians raved about his performance and gave him a game ball, but you have to wonder. he doesn't usually play guard. they ran well against the 49ers, but moving forward they'll play some good from thes and that chemistry along the -- good fronts and that chemistry along the line will be hard to tell going forward.
