What I'll be watching in Giants' game

The Super Bowl champion New York Giants open their preseason schedule tonight at 7:30 pm ET in Jacksonville. I'll be watching, and tweeting, of course, and I will offer my observations after it's over. But to get you ready for the singular experience of watching the game along with me on Twitter, here are three of the things I'll be watching closely in the game:

1. The wide receivers: With Hakeem Nicks still out with a foot injury, veteran Domenik Hixon will start opposite Victor Cruz. Hixon is competing, along with Rueben Randle, Jerrel Jernigan and Ramses Barden, for the No. 3 wide receiver spot, and Nicks' injury is opening an opportunity for all of them to get quality preseason reps. My hunch has been that Hixon, if he can keep his knees healthy, is the leading candidate because he's been around the longest and the Giants have been trying to give him a shot each of the past two years. But we'll see how he performs on the outside, especially compared to the rookie Randle. When the Giants go to three wide receivers, I think they still plan to use Cruz in the slot, so the No. 3 will have to be an outside guy like Mario Manningham was.

2. The running backs: Starter Ahmad Bradshaw says his feet feel better than they have in years, but I still expect the Giants to limit his preseason reps as a health precaution, and to get a look at the backs behind him. While they drafted David Wilson in the first round, I don't think that automatically makes him the favorite to be the No. 2 back behind Bradshaw. He'll have to show NFL-caliber ability as a runner and, maybe more importantly, in pass protection. The fact that Danny Ware has been in the system a few years works against Wilson, but the fact that Ware hasn't shown consistent production during that time opens the door for Wilson.

3. Prince Amukamara: With Terrell Thomas injured, the Giants' 2011 first-round pick looks as though he'll get the start at cornerback opposite Corey Webster. The Giants would like to see Amukamara take a big step forward this preseason, in case Thomas' health is going to be an issue all year and they have to use Amukamara as a starter. I'm also interested to see how they use their cornerback depth behind Amukamara. Will safety Antrel Rolle have to play the nickel corner spot again with Thomas out, or do they have another solution at that spot? And if not, who fills in at safety for Rolle when he moves to corner? A lot of those problems will look a lot smaller if Amukamara looks like he can handle the starter's job.
