LG Zane Beadles vs. DT Calais Campbell

The 49ers negated an excellent front-seven defense against the Los Angeles Rams in Week 1. Not so much in Weeks 2 and 3 against the Carolina Panthers and Seattle Seahawks, respectively.

Week 5 is another test, and the standoff between left guard Zane Beadles and Cardinals defensive tackle Calais Campbell will be one to watch.

Campbell hasn’t necessarily been on the stat sheet much this season. But his presence has been felt, and Pro Football Focus is giving him an 84.4 overall grade — tops within the Arizona front seven.

Beadles, on the other hand, has been one of the weaker links in an otherwise sturdy Niners offensive line. PFF has him graded at a 48.3.

A primary area of concern has been Beadles’ run-blocking ability. Given all the quarterbacking problems San Francisco is enduring, running back Carlos Hyde needs to be a factor. And it will be up to Beadles to ensure Hyde has interior lanes through which to move.
