Cardinals signed OT Haggai Chisom Ndubuisi.
Ndubuisi was part of an international draft combine in London in October and also worked at the UpRise Academy in Africa. At 6-foot-9, 290 pounds, Ndubuisi has tackle size and attributes. The Cardinals will be tasked with developing him with the skills to make those tools work. It says something that Arizona was willing to commit a roster spot to him, but Ndubuisi has no formal high school or college football experience
