Your saying this roster isn't far off from the rosters of the 90s teams that won it all?
First off, the offense was led by Norv Turner, who was a whopping age 38 years old when he joined the Cowboys. He watered a system that supported his quarterback as well as relied upon a dependable run. Today, we have a Scott Linehan, who has an even better pedigree from the start. The current offense is in year one, of his mark on the unit as well as developing points at the beginning of this year. The emergence of a strong running game, and the presence of a talented Tony Romo, Dez Bryant, and DeMarco Murray, and one has a functional three stars as when the '92 Cowboys entered the field. I would place Jason Witten a notch above what was available as to tight end, and above the merit of Jay Novacek.
Those special skills people can produce at a similar level. So, let's look at the offensive line:
John Gesek
Kevin Gogan
Nate Newton
Mark Stepnoski
Mark Tuinei
Erik Williams
Mark Tuinei/Tyron Smith
Kevin Gogan/Ronald Leary
Nate Newton/Zack Martin
Mark Stepnoski/Travis Frederick
Erik Williams/Doug Free
Well, except for the Williams and Free matchup, I'd give the current offensive line equal if not better projections.
If this team was considered a world beater, I would have to conclude at present, that the current Dallas offense should at least be given respects in a general and similar manner.
Now, to the defensive side, rumor control and all set aside...
The defense of 1992, started with their coach. That was Dave Wannestedt, who was a Pittsburgh lineman that opened holes for Tony Dorsett. He led the defense away from the Tom Landry era of the flex, to a 4-3 that was built upon speed, aggression, and an all out sell out for defensive side scheme.
Today, we are witnessing a return to that very same basic defense that was installed with the arrival of Jimmy Johnson to the Cowboys. But, instead of Wannestedt, the Cowboys now have Rod Marinelli. If one doesn't see a direct comparison between the two, here and now, then he has been fooling himself and living out a ring tapper's paradise.
As to personnel when that defense first started up, don't fool one's self. There were few first round types of talent on that defense.
Tony Casillas-1st rounder by Atlanta Falcons
Chad Hennings-11th rounder
Jimmie Jones-3rd rounder
Charles Haley-4th rounder by San Francisco 49'ers
Jim Jeffcoat-1st rounder
Leon Lett-7th rounder
Russell Maryland-1st rounder
Tony Tolbert-4th rounder
It should be noted here, that all but the three first round picked defensive linemen, required a few years to reach respectable and sustained production levels. Charles Haley and Tony Casillas were drafted and developed up by another team, before joining the Cowboys for that team.
Today's Cowboy defensive linemen:
Anthony Spencer-1st rounder
Davon Coleman-undrafted
Ken Bishop-7th rounder
George Selvie-7th rounder by St. Louis Rams
Jeremy Mincey-6th rounder by Jacksonville Jaguars
Terrell McClain-3rd rounder by Carolina Panthers
Nick Hayden-6th rounder by Carolina Panthers
Lavar Edwards-5th rounder by Tennessee Titans
Tyrone Crawford-3rd rounder
Jack Crawford-5th rounder by Oakland Raiders
Henry Melton-4th rounder by Chicago Bears
Demarcus Lawrence-2nd rounder
This assembled group represents a large number of experienced and journeymen in the defensive line.
The productive part should soon be represented by the following group:
Anthony Spencer
Tyrone Crawford
T McClain
Henry Melton
The expectation is that D Lawrence will fill the role played by the former Cowboy, Charles Haley...and more recently, by Demarcus Ware. Those are big shoes to fill, but we'll have to await that further development. But, that element of a dependable pass rush from a consistant producer, is the one element that is lacking in the current roster. This too, will be improved upon by next season...but a workable unit that fits the requirement of:
Crashing outside pressure, aggressive interior that makes reads on the move, linebackers who gang tackle, and safeties that tackle like a linebacker.
I'll let you guys do a little of the work now, and fill in the blanks for the secondary in comparisons...
