Arvell Reese, Caleb Downs went from star teammates to being on opposite sides of rivalry

For 27 minutes on the night of April 23, it seemed possible linebacker Arvell Reese and safety Caleb Downs would be able to share a moving van from Columbus, Ohio, to East Rutherford. 

Instead, the two former Ohio State teammates will begin their highly anticipated rookie seasons on opposite sides of a storied rivalry instead of together in blue, as Reese’s Giants host Downs’ Cowboys on “Sunday Night Football” in Week 1. 

The Giants drafted Reese with the No. 5 pick (at 8:32 p.m.) and right guard Sisi Mauigoa with No. 10 (8:59 p.m.) — twice passing on Downs, who was left for the eager Cowboys on a trade up to No. 11. 

“I was in the back room when the pick was made, and I did think about [teaming up], like ‘Dang, that would’ve been nice,’ ” Reese told The Post. “Then again, we got Sisi, and Sisi’s a dawg. There’s no wrong pick.”
