Thin-framed, small-boned and short-armed with minimal muscular development. Lacks ideal size and strength for a safety and quickness and burst for a corner. Average press strength to re-route receivers. Allows separation at break points — late to transition out of his pedal. Too grabby. Selective hitter — shows up in spurts. Not a physical tackler. Tends to propel his shoulder into ball carriers and needs to do a better job securing tackles.
