Fill-ins, injury substitutes will have big Week 8 impact

Hey now! It's starting to look like Week 8 will feature a handful of personnel changes with the potential to help fantasy owners desperately looking for an infusion of new blood to help turn a season around at the midway point -- or to help those already in control nail things down.

Not all change, of course, is good. Matt Hasselbeck's replacement, Seneca Wallace, appears to be locked in for a three-week run, but I wouldn't touch him with your 10-foot pole. There are also indications the Redskins are using the bye week to take a close look at Jason Campbell. The second-year man could replace Mark Brunell next week.

Wali Lundy earned a start this week with a strong effort in relief of Samkon Gado last Sunday. The tables could just as easily be turned this week.

But other changes. ... Well, they might hold a little more promise. Here are five changes -- or possible changes -- that I find much more interesting:

1. Romo Time! The Tony Romo Era officially began in Dallas Monday night with the start of the second half. It continues Sunday night in Carolina.

Truth be told, it's hard to imagine Drew Bledsoe starting against the Panthers. If the immobile veteran was unable to sidestep an unblocked Michael Strahan, I don't see him faring any better against an unblocked Julius Peppers.

Parcells said he's not nervous about starting Romo. As the Associated Press suggested Thursday, confidence is not an issue with Romo. Neither is mobility, Bledsoe's biggest weakness. Romo also has a quicker release, all of which should lead to fewer sacks -- and, as Owens hopes, more passes coming his way.

The knocks on Romo are his lack of experience, average arm strength and a tendency to make what Parcells calls "impulse" throws.

Get used to both the positives and negatives. We'll see plenty of both as long as Romo remains under center -- which should be for the long haul.

According to Yahoo! Sports correspondent Jason Cole, one long-time Parcells observer explained it like this: "Bill isn't a wishy-washy type of guy on this stuff. He makes the decision and sticks with it. He knows that they're not going to be anything more than a mediocre team with Bledsoe in there. He's not going to waste his time with that unless Romo just falls on his face."

As for Sunday night's game? This might not be the best week to start him. But Romo, who spent considerable time working one-on-one with T.O. this summer (when the mercurial wideout was staying late after practices in his return from an injured hamstring) will get better. And Owens will, too.
