Giants’ cornerback battle heating up at training camp

Observations from the Giants’ training camp practice on Tuesday .

Allen Robinson and Gunner Olszewski — two veterans fighting for jobs at the back end of a young receiver corps — came to life during the joint practices.

Tuesday, Robinson caught a floater in the back of the end zone, and Olszewski had a catch-and-run slant for a touchdown, after which he started shouting at a “gray-hair” coach on the Lions sideline. QB Drew Lock made both throws.

QB Daniel Jones was “sacked” twice — maybe three times — during the first two 11-on-11 periods. On one, Jones tried to dump the ball to Devin Singletary, and it was batted in the air and should’ve been intercepted by the Lions defensive line.
