David Lee has returned to his role as the Bills quarterbacks coach after spending the last two seasons as the Jets quarterbacks coach, where he spent a great deal of time tutoring Geno Smith.
While Lee was complimentary of the progress Smith made late in the 2014 season, he didn't have any issues opening up about Smith's struggles as well.
“Rex and I talked about it. He had some inconsistency, and the up-and-down part is what killed us,” Lee told the Bills' official website. “He would get loose with the football. We played good enough defense to win over there both years, but his play, it’ll cost you and it cost us.
"But he also did some great things. The last five games this season he was the seventh-rated passer in the league. He had a perfect passer rating in his last game at Miami. The potential and ability is there.”
Smith had a 97.9 passer rating over the Jets' final five games in 2014. However, he was benched in favor of Michael Vick for a stretch this season and finished 29th in the league with a passer rating of 77.5.
