As far as La'El Collins is concerned, playing tackle is like riding a bike. Last Thursday, LSU's starting left guard for 13 games last season got back on the bike and pedaled happily away. La'el Collins move to left tackle is the key to LSU's offensive line. "It feels natural," said Collins, a 6-feet-5, 310-pound junior who played left tackle in high school. His move back outside will be watched carefully by coaches during spring practice and is the key to coherence in the offensive line for 2013.
