Consider Thursday’s practice to be the first time Fields has looked considerably better than Andy Dalton, who didn’t appear as comfortable in the two practices against Miami as he has against his own defense. Dalton is still having a strong camp overall, but Thursday would best be described as choppy. For example, during the red zone session, Dalton hit Byrd on a nice throw to the corner, but followed that up with a miss to Darnell Mooney before getting picked off by linebacker Andrew Van Ginkel on a pass deflected at the line of scrimmage.
So what does it all mean for the Bears? Well, it means that in one practice on Thursday, Justin Fields looked like the special quarterback the Bears thought they were drafting at No. 11 overall. His full talent – the arm strength, accuracy, athleticism and speed – was all on display, especially in the red zone period.
But it was also just one practice. Fields needs to stack them together before he threatens the Bears’ plan to use Dalton as their starting quarterback this season. That said, the timing of Fields’ breakout practice was convenient, as his next test will be Saturday’s preseason game against the Dolphins at Soldier Field. It will be his first NFL game and the first time he can actually get hit by a defense. Dalton will start, but is only expected to play around 8-10 snaps. Beyond that, it will be Fields’ game into the second half, perhaps even into the fourth quarter.
There are, of course, the usual training camp caveats. Fields has been playing against backups and while he could see a few reps with the starters Saturday, he likely won’t be facing many of the Dolphins’ starters for very long. On the other hand, he was also playing behind a depleted backup offensive line in Thursday’s practice and he hasn’t had the luxury of throwing to Allen Robinson in practice. It goes both ways.
All Fields can do is pass each test he is given. He hasn’t done that every day, but the overall body of work has been encouraging. And if Thursday's joint practice against the Dolphins was any indication, a significant jump could be coming.
