"An NFL head coach has more worries than hours in a day, and for Tony Sparano those might include finding a starting free safety and getting his young linebackers ready to play or wondering if Brandon Marshall will be healthy for the start of training camp in July.

Sparano's concerns might even include his team's growing arrest record because the Dolphins this offseason are averaging one run-in with the law per month and two months still remain before any games begin.

But one thing Sparano definitely doesn't have to worry about is Jake Long.

That's because the blind side of the Dolphins' offensive line is a brick wall that blocks out misgivings and problems.

Long, as he readies to start the third year of a career that already includes 32 starts in 32 games and two Pro Bowl appearances in his first two seasons, is nothing if not steady and reliable and even unfaltering.

So what does Sparano worry about when he thinks of Long?"
