Joe Mixon had a crisp first day. With the Bengals set to put on the pads for the first time next Tuesday, Bengals head coach Zac Taylor used Wednesday's first practice of training camp to ease into amp-up mode. Quarterback Joe Burrow barely threw a ball over five yards in his first two 11-on-11 sessions since last season, but the crispness of his spring work and his chemistry with first-round pick Ja'Marr Chase were on display as 90-degree temperatures blanketed the Paul Brown Stadium practice fields. As limited as the action was, new offensive line coach Frank Pollack's presence could be felt by the urgent tempo of a position group that begins camp splayed under a microscope. The pace already been predicted before practice by one of the two players Pollack coached when he was here in 2018.
