4. Davis Mills, QB, Houston Texans
Davis Mills is the outlier on this list. He's the only rookie quarterback that wasn't drafted in the first round to start a game this season.
No one expected Mills to play this early, but the Deshaun Watson situation coupled with an injury to Tyrod Taylor has forced him into the starting lineup. And he, like the others, has had a roller coaster of a rookie campaign so far.
Mills is coming off an outstanding performance against the New England Patriots in Week 5 in which he finished 22-of-29 for 312 yards, three touchdowns, and no turnovers.
Unfortunately, that came just one week after his disastrous four-interception outing against the Buffalo Bills. Mills has been good in two of his three starts which is why he lands where he does on this list.
That lone horrid start, however, drops him a couple of spots.
3. Justin Fields, QB, Chicago Bears
Justin Fields has started three games this season and is the only rookie QB with a winning percentage above .500 after five weeks. Of course, that doesn't tell the whole story, but Fields has done enough to show his potential in those three starts.
While his raw numbers may not look too impressive (1 TD, 2 INT, 51% completion, 6.4 YPA), he's probably been a bit better than the stats indicate.
For starters, Fields has been pressured and sacked at a higher rate than any of the rookie quarterbacks, some of which is his own doing while some of it also falls on his team's poor offensive coaching.
Perhaps the best indication that Fields "it" is that he has seven "big-time throws" in just 93 dropbacks. That's tied for the most among rookie signal-callers with Trevor Lawrence and Zach Wilson, although each of them has more than double the number of dropbacks.
Fields has made some impressive plays, and if he gets a little more help from his supporting cast, he could be in line for a big second half of the season.
