BEVERLY HILLS — The Lions will wrap up their second four-day session of team workouts on Friday at Detroit Country Day. Obviously they couldn’t make them mandatory, but those who have attended have discovered how beneficial they are.

The last ones off the field on Thursday were quarterback Matthew Stafford and rookie wide receiver Titus Young. The pair spent 10-15 minutes with Stafford teaching Young some of the basic passing routes. Young, a second-round draft pick out of Boise State, seems to have good hands.

Before Stafford worked with Young, he was one-on-one with rookie running back MIkel Leshoure, a second-round pick out of Illinois, showing him the basic run routes.

With no offseason training due to the NFL lockout, it’s the rookies who can benefit the most from these sessions. Although Stafford admitted it keeps him sharp too.

With Michael Knight of the Art of Strength running the workout part of these sessions, there has been much structure and much sweat.
