Cardinals to shift Veldheer to right tackle, Humphries to left tackle

The Arizona Cardinals will shift veteran left tackle Jared Veldheer to the right side in 2017, making room for 2015 first round pick D.J. Humphries to protect Carson Palmer's blindside.
Veldheer has had a very solid NFL career to date, posting good PFF grades of more than 80 in 5 of the last 6 seasons (the lone exception being an injury shortened 2013 campaign).
After being inactive for the entirety of his rookie season, D.J. Humphries posted a PFF grade of 70.3 over 13 starts last year, the last 3 of which came at left tackle.
Humphries had his struggles in pass protection, ranking 43^rd of 61 qualifying offensive tackles in pass blocking efficiency for the season (93.4).
Encouragingly, during his 3 starts at left tackle, Humphries did not allow a sack and marginally improved his PBE to 93.6. He posted PFF grades of 73.0, 54.5 and 74.4 in those 3 games.
Veldheer fared better than Humphries as a pass blocker last season, allowing just 1 sack and posting a PBE of 95.3 at left tackle before tearing his triceps in Week 8.
