Look at his efficiency numbers game to game. His completion percentages were lower than Brees and Brady. He struggled for this same reason in his rookie year. Luckily, the Eagles surrounded him with elite WRs to make up for his weaknesses. They had a stacked team last year and that was why they continued to roll after Wentz went down. It was only a matter time Foles caught fire with that team and they got back on track.
