Way back in 2004, Jason Witten began his streak of finishing the season as a top-12 (or better) tight end. He finished 12th among tight ends last season, and the Dallas Cowboys pass catcher is the quintessential low-upside/high-floor guy we're talking about.
J-Witt, who ranks seventh in career receptions in NFL history, is now entering his 15th season. When he started his career, Arsenio was still on TV. Don't fact check that.
In those first 14 seasons, Witten has missed one game. One. Game. That's about as safe as it gets.
numberFire projects him to regress a bit more this season, ranking him 16th among tight ends. The good news with Witten is that he is currently going undrafted in most leagues, so he will be easily attainable via free agency or with a late-round selection. He will be stream-worthy many times during the season.
