He wants to get there, but Prince Amukamara knows he’s not there yet. The Giants will not ask him to shadow Dez Bryant all over the field Sunday in what Amukamara believes is “definitely a big statement game for our team’’ as the Cowboys arrive attempting to end the Giants’ four-game winning streak and knock them out of contention in the NFC East. There will be plenty of plays where the two are locked up together, but mostly Amukamara figures to stay at his right cornerback spot and take who lines up across from him, be it Bryant, Miles Austin or Terrance Williams. “I think that’s when you know you’re starting to get that idea that you’re a lock-down corner, that the coaches trust you enough to follow the guys around,’’ Amukamara on Thursday told The Post. “It either means you have a weaker link at the corner position on your team or you have so much trust in that one corner that he can shut down the wide receiver.’’ The trust in Amukamara is growing in his third season and there’s no doubt the Giants want to see him on Bryant as often as possible, although they aren’t going to bust up their defensive scheme to do it. Their other options at corner are Terrell Thomas, who has usually handled the slot receiver in his comeback season, and Trumaine McBride, who returned to practice after missing Wednesday’s session with a hip pointer. McBride has filled in decently for injured Corey Webster — who likely will miss this game with a high ankle sprain — but asking him, at 5-foot-9 and 185 pounds, to battle the 6-foot-2, 222-pound Bryant might be asking too much. “He’s grown up,’’ defensive coordinator Perry Fewell said of Amukamara. “Prince was the little brother and he still may be the little brother to most of these guys, but he’s made some plays.’’ Gone are the feeble passing attacks the Giants feasted on in their four-game winning streak; Tony Romo can slice up a secondary. His most dangerous weapon is Bryant, who has 52 catches for 749 yards and eight touchdowns and once he gets on a roll he is tough to stop.
