I think a guy like Jacob Rodriguez the LB from Texas Tech is a textbook Dan Campbell player. He's a high motor, good character guy, who seems to love the game of football and have a strong work ethic. As well, he could slide in and be our WLB to replace Anzalone. Gabe Jacas also fits those traits but plays at another position of need as a DE/Edge. Jacas also gives them what they covet in an edge-setting lineman, who can stay in on all three downs and play against the run.
I'd personally be fine enough with either Jacas or Rodriguez. I'd prefer Jacas as he offers more ability to get at the QB and disrupt passing plays. He had 11 sacks, 41 total pressures, and 22 hurries. I'm really intrigued by his pass rush abilities. I doubt he makes it to the Lions pick at #50, but would run the draft card right up to Goodell and make the pick.
