No diabolical experiments are planned but the Giants are hoping Aaron Curry, in the words of general manager Jerry Reese, can “reinvent himself’’ now that he has officially signed on in his attempt to resuscitate a football career on life support. Curry did not leave the team facility after working out Thursday for the Giants. He stayed around an extra day, watched the two rookie mini-camp practices yesterday before going inside in the afternoon to sign a one-year contract to become the newest Giants linebacker. “He passed the physical for us and had a pretty good workout,’’ Reese said. “We think we have a good opportunity for him here to see if he can reinvent himself a little bit and bring something to this linebacking corps.’’ Curry, 27, is an interesting prospect in that back in 2009 he was the No. 4 overall pick in the NFL Draft out of Wake Forest. He did not pan out in two years with the Seahawks and was traded to the Raiders during the 2011 season. He hasn’t played since he was released by the Raiders last November after playing in only two games. In his disappointing career, Curry has 5 1/2 sacks and 190 tackles in 48 games, slowed often by knee issues. When asked if Curry is coming off serious knee surgery, Reese said, “Yeah, I think so’’ before deferring to the team’s medical staff. “I think that has been part of the problem, he’s had some knee injuries that hampered him a little bit,’’ Reese said. “He’s a very mature guy and he’s looking forward to the opportunity.’’ Curry did not look to be in prime shape as he stood and observed the rookies. Reese said Curry is 265 pounds and “needs to drop some weight,’’ noting he weighed 255 coming out of college.
