Steelers plan to give Russell Wilson first-team reps in preparation to ...

"[Russell Wilson] is in consideration this week. We'll see where that leads us," he said.

Tomlin later added: "I'll acknowledge that Russ proved his health last week, and we're looking hard at him this week. It is up for consideration."

Fields has started the first six games of the season, helping the Steelers to a 4-2 start but the offense has been inconsistent, particularly through the air. In the past two weeks, Fields has thrown for fewer than 150 yards and completed fewer than 60 percent of his passes. The dual-threat has done most of his damage with his legs, including two touchdowns in Sunday's win over Las Vegas.

"Justin has been really good, and we've been good at times, but not to be confused with great," Tomlin told reporters on Tuesday when asked why Fields had not done enough to be named starter despite a 4-2 record.

"This is a competitive league, man. We're trying to position ourselves to be that team, and we've got a player with talent, who hadn't have an opportunity to play, so we're going to explore those things. Sometimes it doesn't have anything to do with what Justin has done or has not done. Justin has been an asset to us. Last week, for example, his ability to utilize his legs by design and by ad lib was a significant component of that game. He rushed for 50-plus yards and two touchdowns. … We're appreciative of that. We're appreciative of how he's taken care of the ball. But we're just looking at all of the people at our disposal. The same way we do at any position."

The question for Tomlin is whether he believes losing the dynamic rushing element Fields provides might be worth it if Wilson can bring more to the passing attack. It's also possible the Steelers could utilize both QBs Sunday night against the Jets, something that Tomlin did not rule out on Tuesday.
