Back in the spring of this year (April, maybe?) Cassagrande wrote an article about an interview he had with Tua's dad. As it ends up, Tua is naturally right-handed but his dad forced the switch.
Anyway, in the same article Jacobs isn't mentioned, but Smith, Stabler, and Shula were as I recall.
"How Tua became left handed" through Google should pull it up...
