I think Robertson is universally considered to have raised the level of his game after a pretty slow start, and Rivers and Benson haven't shown much if anything, good or bad yet. They are going to have their time, and I don't think they can quite be judged yet. I'd put Robertson, Smith and Big Mike about equal at this point, adequate starters that have been moderate disappointments given their lofty draft position. Who knows, maybe Warrick will make the connection with some QB late in his career and finally display his talent.
