Current Cowboys who'd help us win in our Super Bowl losses

[Cowboy from New York]

Man! Has it been slow the last few weeks as far as new information and I've turned the draft scenarios over in my head so many times I've lost count. Anyways, don't know why but I was thinking of a question to throw out to you guys to kill some time on this slow weekend, here it is:
What one Cowboy who is CURRENTLY on the roster now would have been of the greatest help to snare victory from defeat and help us win each game in our three supe bowl losses?

Here's my take:

Super Bowl XIII Dallas 31 Pitt 35
No brainer here, we already had Too Tall, Randy White and Harvey Martin on our d-line so the pass rush spots were covered. Look at the stats, Lynn Swann had 7 catches for 124 yds and a touchdown, Stallworth had 3 catches for 115 yards and 2 touchdowns including a 75 yard touchdown catch. No Deion around for us so I gotta go with Newman for pass coverage.
Although you could say Witten wouldnt have dropped the pass Jackie Smith did.
Super Bowl X Dallas 17 Pitt 21
Lynn Swann had 4 catches for 161 yrds with a 64 yard TD bomb in there. Lot of famous Cowboys on this d-line although Jethro Pugh was probably long in the tooth this many years after the ice bowl. We also had Staubach get sacked 7 times with Rayfield Wright and Ralph Neeley manning the 0-tackles.
Guess I'd go with Newman again at the corner instead of Mark Washington.

Super Bowl V Dallas 13 Balt 16
QB Craig Morton completed less than half his passes and threw 3 picks. I have my doubts about Bledsoe's mobility but Dallas only allowed to sacks this game and Bledsoe would have almost certainly played better than Morton did especially considering Bob Hayes was on this team.

I know it was a little weak going with Newman for two of the three games but Swann and Stallworth did kills us (with some bad PI calls I know)
Anyway, tell me what you guys think.

SB X
Julius Jones over the tandem of Newhouse and Preston Pearson. I think that might have made up that 4-point difference.

SB XIII
Witten. Not only does he hold on to that TD from Staubach, he catches six or seven more passes.

SB V
I didn't see this game, but as bad as both teams played, who cares?
