"I can't answer the questions you want me to," he said after a streak of queries on Saturday's conference call regarding the deployment and health of various cornerbacks and safeties. What he could say is that after losing two rookie safeties -- one for the season and one likely for the rest of the preseason -- he has no firmer grasp on how that position will be filled than he did five months ago. "The level of concern has been there since Day One because of the nature of where we are," Coughlin said. "Certainly there is concern." And when it comes to the equally thin numbers at cornerback, Coughlin said: "You can count as well as I can. And you can never have enough of those guys anyway." Second-round pick and projected starter at safety Landon Collins suffered an MCL sprain in Friday's preseason loss to the Bengals. Coughlin did not have a timeline for his return, but it is an injury that typically takes close to a month to heal. For the rookie, that means missing valuable preseason snaps. Also on Friday, fifth-round pick Mykkele Thompson injured his Achilles. He'll be placed on injured reserve and is done for the season. The Giants also are monitoring the health of cornerback Jayron Hosley, who left the game with neck and head injuries. Coughlin said he hoped Hosley would be able to return quickly after playing well. He was less optimistic about previously-injured Prince Amukamara (groin) and Chykie Brown (knee) practicing this week. All of which leaves the Giants with only one healthy player in the secondary who has ever started an NFL game: the perpetually sore Dominique Rodgers-Cromartie. "Those are the guys we have," Coughlin said, "and we'll work hard to get those guys ready to play." Receivers catch grief Upset with the entire performance against the Bengals, Coughlin singled out the play of the wide receivers -- a supposed strength of the team -- as one of the bigger disappointments. "I thought their execution left a lot to be desired," he said. "I thought the details and the route-work was not very good." Odell Beckham Jr. and Rueben Randle were both without a catch and Preston Parker dropped a pass that could have given the Giants an early first down and perhaps changed the tenor of the night. Randle, Coughlin said, was playing in pain from tendinitis in his knee and "not himself." He likely will be rested several days this week. Giant steps How about the rookie left tackle? "I thought [Ereck] Flowers did OK," Coughlin said of the team's first-round pick who is thrust into a larger role than expected . . . As for the rest of the starting offensive line, he was not as positive. "As a group we weren't able to execute together in any capacity that allowed us to have total success with the play" . . . The Giants return to training camp practices at their facility Sunday for the first time since last Saturday.
