After an impressive rookie season, Prescott disappointed last year. He went from fourth in the league in YPA to 20th, his completion percentage dropped by five points and, worst of all, his interceptions ballooned from four to 13. The only thing that kept him afloat was a second straight year with six rushing touchdowns, along with an uptick from 4.9 YPC to 6.3. While his decision-making was suspect, especially in the red zone where he threw three interceptions (2nd in NFL) and took six sacks (3rd), Prescott didn't get a lot of help from the rest of the offense. The line lacked depth and suffered injuries, most significantly to Tyron Smith; Dez Bryant caught just 52.3 percent of his targets and the wideouts averaged a mere 3.8 yards after catch; and, of course, Ezekiel Elliott was suspended six games. Without Elliott, Prescott broke 200 yards passing just twice and threw seven interceptions as defenses dropped into coverage without fear of the running game. Smith missed the first two of those games and Prescott was sacked 12 times, accounting for more than a third of his season total. The Cowboys added depth to the line this offseason, but health is probably more important. Big changes came to the pass catchers - namely, Bryant was released and tight end Jason Witten retired - but there is seemingly little to get excited about. The Cowboys added Allen Hurns, who hasn't played a full season since 2014, and Tavon Austin, whose best position might be punt returner. Incumbent starter Terrance Williams is coming off foot surgery and was arrested in May. In a run-first offense, Prescott might be relegated to a game-manager role, but his rushing ability at least gives him some stability.
