Why did the Giants cut Greg Jones, who was a starter in the 2011 season-opener, and keep so many defensive ends on their roster?
-Harrison

Dear Harrison:
Several reasons. The Giants didn't have room for eight linebackers on the roster. Someone had to go and Jones was the odd man out. Some people would make the argument that Jones could have stayed and Adewale Ojomo could have been waived. But Ojomo showed tremendous promise as a pass rusher in the preseason. One axiom the Giants adhere to is you can't have enough pass rushers. They've demonstrated that with Osi, Tuck and JP. You're more likely to find a linebacker on the open market than a premier pass rusher. Also, the Giants have several good young linebackers.

I'm confused as to when an injured player can be put on the PUP list, and when a player needs to be put on injured reserve. What are the different rules for each?
-Dennis

Players can be put on the PUP (physically unable to perform) list in training camp if they haven't stepped foot on the practice field. If they are placed on the reserve/PUP list – as Chris Caty and Travis Beckum were last week - on the day after Week 6 (October 16) and up until the day after the ninth regular season weekend (November 6), players on that list may begin a 21-day practice period.  During that time they are still technically on Reserve/PUP (so they aren't removed from PUP), but they cannot play in a game until they are activated from PUP. Players on injured reserve do not have that option – they are out for the season, except for the one player designated by the club who can return after Week 8. The Giants do not yet have such a player under that rule, which is new this year.
