Could a day three rookie land a starting spot for the Cardinals? One site thinks so

D.J. Humphries growth is one of the most important parts of the Arizona Cardinals 2017 season.

The expectation is for Humphries to take over at left tackle, where in a short three games in 2016, he was more than solid.

Humphries play is important, but his not being ready wouldn't exactly kill the season, as Jared Veldheer is still on the roster, and if it is noticed soon enough, a quick switch back is imminent if the Cardinals want to have a good 2017.

Unless you're Bleacher Report, where picking a surprise starter for every team means bypassing the logical switch back and instead finding rookie fifth round pick Will Holden replacing Humphries at left tackle:

In theory, the left tackle spot will be manned by 2015 first-round pick D.J. Humphries. The same Humphries who tied for the NFL lead among tackles last year with nine sacks allowed.In other words, Humphries' grip on the starting job isn't exactly iron-clad.

Don't count out Holden, a three-year starter from the SEC with experience on both ends of the line.

Holden is a nice developmental pick, but no rookie offensive lineman has won a starting job under Arians (outside of Jonathan Cooper). Holden would have to bypass both Veldheer and John Wetzel in order to crack the starting lineup.

Meaning, to me, barring injury, I don't see Holden or fellow rookie Dorian Johnson cracking the 2017 starting unit.
