A player, coach or issue that should be on your radar as training camp approaches.
Now Pittsburgh needs answers -- and quickly. With training camp set to begin later this month, the Steelers worked out veteran offensive tackle Flozell Adams but didn't sign him to a contract. If there is no movement in free agency, Essex could be the top choice to replace Colon.
Essex started all 16 games at right guard last season, but his starting job this year was already in jeopardy. Pittsburgh drafted rookie Maurkice Pouncey in the first round (No. 18 overall) with the anticipation that the Florida product would eventually take over for Essex, who has played on the first team this spring. Colon's injury could speed up the process and give Essex a chance to work at right tackle in training camp and the preseason.
"When you look at Essex, I kind of like him because he's smart and he's versatile," said Scouts Inc.'s Matt Williamson. "In a pinch, he can probably play any of the five positions. But he's going to get exposed if he's there too long for any of them.
"He moves pretty well, although I think he carries too much weight and a bigger spare tire than you'd like to see [for an offensive tackle]."
For an offense that recently traded receiver Santonio Holmes and will be without quarterback Ben Roethlisberger for at least four games, solving the right tackle issue this summer would be a huge plus.
