1. The Patriots do want to keep Anderson, but they've set a value and won't move too far off it. The value is tied to Anderson not being a full-time player over the course of 2011 (47 percent of snaps), and their presumed belief that he isn't a full-time player. Anderson is obviously hoping for more, hence his visits.
2. The Bills might be able to offer him something more than the Patriots -- a starting role opposite Mario Williams. That's pretty appealing from this view.
3. In terms of the four visits, the main thing that stands out to me is that it speaks to the demand for pass rushers. I don't think it's good thing when it comes to the Patriots' chances to retain him.
4. I thought Anderson played better against the run than anticipated last year, but understand why there would be some doubts about his ability to do so with a more expanded role.
5. The Patriots signed Anderson to a 1-year, $1.375 million contract last year, which turned out to be good value. Those types of deals are often described here as low risk, high reward, but here is another point to consider: When the Patriots execute those contracts, the upside is limited (if the player performs well, the team is at risk of losing him the next year). So maybe it would be best described as low risk, moderate reward.
