Giants DE Jason Pierre-Paul had back surgery Tuesday morning to deal with a lingering injury. ESPN's Adam Schefter reported that JPP played through the injury in 2012 and had multiple epidurals during the season. Pierre-Paul said they decided to go for the surgery when the pain didn't go away this offseason. He's expected to be ready for the season, but it's not clear how much prep time JPP will have. That's particularly concerning when you consider that HC Tom Coughlin accused the player of arriving at camp out of shape last summer. (Pierre-Paul refuted that.) His back issues also date back to college. New York's starting right DE dropped to just 6.5 sacks last season after busting out for 16.5 in 2011. Expect JPP to drop down our preseason rankings a bit on this news. We'll be watching throughout camp to reassess his fantasy football value as an IDP.
