Round 4, Pick 103
After signing Darius Philon and retaining Rodney Gunter, the Cardinals need for defensive linemen is less prevalent than before. But that doesn’t mean general manager Steve Keim shouldn’t add to the unit after doing so in the first.
Cue Renell Wren, an excellent depth option earlier in his career with the ability to be a high-level starter by the middle of his rookie contract. Standing tall at 6-5, 318-pounds, Wren is a well-built product with the athleticism to boot. At the combine, Wren recorded a 5.01 second 40-yard-dash, 30 reps on the 225-pound bench press, 32-inch vertical jump, and 7.65-second three-cone-drill.
During his four-year career at Arizona State that featured two seasons as a starter, Wren tallied 69 total tackles and 4.0 sacks. Per Pro Football Focus he had 47 run-stops, 32 quarterback hurries, and four batted passes. He also finished the 2018 season with a 69.5 PFF grade.
NFL Media’s Lance Zuerlin views Wren as a “boom or bust” product, in his combine write up he said;
"Enticing prospect offering size, strength and athleticism to entice NFL general managers who covet elite traits over college production. Wren’s play was uneven while aligned on the nose in 2018, but he should benefit from a move to defensive tackle in an odd or even front as a pro. The cheat code in unlocking his ability and production might rest in a team’s ability to correct his hands and feet while improving recognition. With all things considered, “boom or bust” might be an appropriate tag for him."
