He was overpowered at the point of attack on several occasions. * Cowboys first snap, 12:42 first quarter: Arkin is pushed back into the backfield by Tommy Kelly, causing DeMarco Murray to change his path on a simple zone running play to the right. * Cowboys second snap, 12:05 first quarter: Arkin is jolted again in pass protection by Kelly. Play is a success because Romo delivered the ball quickly to Bryant. * Cowboys second snap of second possession, 2:17 first quarter: Arkin is supposed to hold up Kelly for a 1-count before releasing to block for the screen. Instead, he barely touches Kelly and Kelly sacks Romo for a 12-yard loss. These are the types of plays that can potentially ruin a season. * Cowboys sixth snap of fourth possession, 4:15 second quarter: Arkin is unaware of a tackle-end stunt on Raiders line on a Cowboys inside zone run. Carl Ihenacho stunts to the inside and Arkin spots him too late and must hold him. Despite the hold, the play is still blown up on rather simple inside movement. All of this is not to suggest that didn't battle hard last night. He certainly played more than anyone on the roster. It is simply to sound the alarm on this entire "Phil Costa, Kevin Kowalski, Bill Nagy, and David Arkin center project" that has gone on long enough. There is simply not a center who is NFL starting quality in the group from what watching these four players battle over the course of two seasons of football. The Cowboys are clearly marginalizing the job of center in an "anybody can do this" sort of way, and it is not working out. There is a reason that the Cowboys' playbook has been a disaster in most road games recently, and it is because they are outclassed on the interior of their line. They think they have addressed the two guard spots, but early returns are spotty. The center position, though, is either very poor or a complete disaster. Still, after having an entire offseason to hope and dream that it would be better because of big work in the weight room. It would still be prudent to let Costa prove that he is either the same guy who was struggling so much last year or a player who is developing. But, based on what I have seen at training camp, I am going to ask him to prove it with live ammunition. In the meantime, the Cowboys need to be taking this issue far more seriously than they did in the 2011 training camp when they fooled themselves into believing that Costa would be fine. But, none of the four in the group look like promising prospects from what they have shown in their action in games of both the preseason and regular season variety. Not exactly the same viewpoint as Broadus. Just sayin'
