Dan Morgan actually had some speed.  Not sure if you are talking about playing style, personality, or looks.  BC they do not look that much alike IMO, but they have similar ball instincts and enthusiasm.

I remember a kid that played for Duke in the 70's who was drafted by the Baltimore Colts.  He played fullback at Duke but the Colts made a Middle linebacker out of him.  Leman reminds me of him.  That guy was so mean his own team didn't want to scrimmage with him.  Does anybody have any idea who I'm talking about? I can't remember.  He finished up his career with Miami, but he was all out when on the field and took no prisoners.  He once hit some guy who ran out from the stands and picked up the football.  He nearly killed him!!

I love Leman's motor, desire, and attitude.  He has impressed me so far, but the fact is that Dan Morgan was a straight up beast, and Leman has a little ways to go before I start comparing the two.
