Gross plays RT, so he will probably go up against Ellis mainly. In the Panthers 1st game of the year vs Atlanta, thier LT hurt his knee and is out for the year. When this happened, they moved Gross to LT for the rest of the game. John Abraham owned him when they did that. Since then, they moved him back to RT and have some journeyman playing LT.
Nevermind, according to the panthers website, they have gone back to gross as the LT now. Wharton was the starting LT before he got hurt and put on IR after game 1.
