No Victor Cruz for the organized team activity practices or the minicamp? No Hakeem Nicks for the OTAs? No problem, as long as Rueben Randle was on the scene. Randle, the second-year receiver, rose above all other Giants receivers this offseason, which concluded Thursday with the end of a three-day minicamp. “Rueben emerged from a guy that showed flashes at times,’’ offensive coordinator Kevin Gilbride said. “He always caught the ball well but maybe didn’t always run the routes as precisely, as crisply, as you wanted. He didn’t have quite the understanding you wanted. [This off-season] he looked like a guy that has been here for five or six years. He really benefited from the opportunity. His whole demeanor, his whole professionalism, was outstanding.’’ The Giants have big plans for Randle, a second-round pick last year. He caught just 19 passes as a rookie and, at times, teammates and the coaching staff were frustrated by an apparent lack of urgency. The Giants hope to sign Cruz to a long-term deal and expect Nicks, who is coming off offseason knee surgery, to arrive at training camp in much better condition. Gilbride said even with Nicks and Cruz on the field, Randle has earned himself playing time. For workouts in the spring, not having Cruz or Nicks (who failed to show up for all nine OTAs) allowed younger receivers to gain experience. Gilbride said not having his two starting receivers was “a relatively minor thing,” but he did not discount that their absence hurt. “The thing is, they haven’t been working, they haven’t been listening, they haven’t been growing, they haven’t been developing, they haven’t been receiving the coaching that they need to get better,’’ Gilbride said. “To be quite frank, both of them need it. The absence, not being here, has hurt them and because of that, it’s hurt us.”
