I know this point might have been mentioned in the past, however, it seems to get overlooked quite a lot....
The key word is "continuity"... which is what the Cardinals have lacked in the OL for several years... Whether it be injuries or players not panning-out.. they've constantly have patched work that position with UDFA and those who were beyond their prime.... I feel given a chance with Davis, M. Brown, Ross, Wells, E. Brown, Step, and Lecky... they all have that talent and athleticism... have the passion...... Along with cohesion... the essence of better coaching will come into play since Loney is proven.. whereas... we all know Lindsey didnt have any credibility... especially since he inherited the role from Wylie out of default.... I think if Green and Wylie got along better..the OL would have progressed by leaps and bounds by now, but instead regressed since they hire someone who couldnt even make the team as a player out of training camp....
Then.. now to have an RB of "the Edge's" calibre is enough to elevate their game... I believe they werent motivated at times knowing that they were blocking for someone who is less than he once was which was Shipp and someone who seemed to be a total coward such as Arrington... Now.. they know they're fully aware that they have someone of Edgerrin James magnitude.. that they will go all out to be on highlight reels as the one who delivered that big block to create a game breaking run... or a 3 yard scamper into the endzone......
People tend to forget about what happened w/Barry Sanders between the '91 and '92 season.... The Lions in '91 finished 12-4 and went to the NFC title game to ultimately be massacred by the Red Skins.. one of the main reasons why the Lions advanced that far was the continuity of a unit that had been together for several seasons which included Lomas Brown before he hit his prime, Kevin Glover, and Ken Dallafoir..and 2 vastly emerging players who were becoming Pro Bowl talents of their own... that being Mike Utley (we all know his fate) and then Eric Andolsek who died during that offseason when a motorist ran him over as he was mowing his lawn (IIRC)....
So.. with 2 of their top OL no longer on the squad to start the '92, they were forced to draft Larry Tharpe and also rely on a couple other unprovens at that position which caused them go to 5-11 as a result....Then after that they signed a smattering of veterans and drafted OLs between the 3rd-6th rounds and all began to gradually establish that continuity and began advancing to the play-offs the following few years w/some frequency... Sanders would reward the OL with Rolex watches when he would earn another leading rusher trophy.....
So.. essentially.. I think w/continuity, better coaching, and a sense of motivation to have the Edge in the backfield..the Cardinals OL isnt too as far out as it may appear on the surface.....
