Jeremy Lin was officially introduced as a Houston Rocket today. As you can see, Lin has decided to wear #7. Why #7? While Lin wore #17 with the Knicks and #4 at Harvard, he sported a #7 his rookie season in Golden State. Why not stick with the jersey number he got famous wearing? Maybe he wants to stick it to the guy on the Knicks who called his contract ridiculous. Or maybe Lin is a student of the game and wants to respect the memory of Houston great Mario Elie. Or – and this is the most likely scenario – some third thing.
