NFC North: Jenry Melton

Earlier Thursday, we looked at four established NFC North players who reside on the proverbial roster bubble. Now, let's take a broader look at some key questions our teams face in determining the final composition of their rosters.

Will the Bears wipe out a good bit of their 2009 draft? Defensive lineman Jarron Gilbert, receiver Juaquin Iglesias and defensive lineman Henry Melton were the Bears' top three picks of that draft. They've all been invisible this summer and certainly haven't done anything to earn roster spots. Whether one is reserved for them is another question.

Can the Bears find room for special-teams stud Tim Shaw? He had 30 tackles on special teams last season but isn't much of a factor on defense. But he would qualify as a specialist, and there isn't always room for one on a 53-man roster. Do the Bears feel comfortable using him at linebacker, especially considering preseason injuries to Brian Urlacher, Lance Briggs and Nick Roach? Uncertain.

How many running backs will the Detroit Lions keep? We know that Jahvid Best is the starter, and veteran Kevin Smith would be the likely No. 2 if he were completely healthy. But does Smith's offseason knee surgery make the Lions nervous? And if so, do they keep five backs behind Best -- Smith, Maurice Morris, Aaron Brown, DeDe Dorsey and fullback Jerome Felton -- or does one get released?

If they keep an extra back, could the Lions take a roster spot from the quarterback position? That's not out of the question. The Lions have established Shaun Hill as the long-term backup to starter Matthew Stafford. So is there any reason to keep Drew Stanton on the roster?

Will the Green Bay Packers keep five tight ends? We mentioned the possibility of veteran Donald Lee meeting the end of the line. It's also possible that Tom Crabtree could be sneaked onto the practice squad. But you could make an argument that all five tight ends are among the Packers' top 53 players. General manager Ted Thompson has made odd numerical choices before; last year he kept three fullbacks for what is mostly a one-back offense.

Will both players who entered 2009 competing for the right tackle job be cut? It's very possible that Allen Barbre and Breno Giacomini have played their way off the team. This year's backup tackles are more likely to be Bryan Bulaga and T.J. Lang.

How will the Minnesota Vikings establish more depth at cornerback? Right now, their starters are Antoine Winfield and either Lito Sheppard or Asher Allen. The nonstarter in that group is the likely nickelback, but beyond him the Vikings have no viable candidates for depth. A waiver claim or trade would seem a near-certainty.

How many receivers can the Vikings keep? Bernard Berrian and Percy Harvin are locks. You would think Greg Lewis makes the team, along with Greg Camarillo. Will Javon Walker make the Week 1 roster as a No. 5 receiver? Or would the Vikings be wary of guaranteeing his 2010 salary? Signing him back as early as Week 2 would allow them to pay him on a weekly basis.
