Walker came to Indiana after three seasons with James Madison and immediately proved he was ready for the jump. He’s a linebacker who is built like a safety, but he can cover on third downs and shine on kick-cover teams. Walker brings solid play recognition and can be a slippery target to find for blockers. He has above-average range and is capable of spying quarterbacks, but downhill running attacks will test his block take-on and tackle strength. His size is a concern, but he has a nose for the football and athletic ability to compete for a role as a special-teamer with nickel linebacker potential.
