Los Angeles Chargers QB Justin Herbert is one of the best QBs in the NFL and will likely go down as one of the best QBs in Chargers team history. And he's not even 28 years old yet. 

We've seen him add new skills to his repertoire throughout his six-year NFL career, but I think we can identify a new one for this season that is both helpful and a little worrisome.

Even before today's win over the Tennessee Titans, Herbert was averaging a career high rushing attempts per game (4.6) and rushing yards per game (31.0). Both numbers will undoubtedly go up after Herbert rushed 9 times for 57 yards and a touchdown in Nashville.

This increase in rushing from the QB has been useful, if not absolutely necessary, in keeping the offense from capsizing after the team took so many injuries at RB and along the offensive line. I also love that it's just one more thing that opposing teams have to prepare for, and one more way to either hold opposing LBs as spies or punish opposing defenses for blitzing.

That being said, and vibes aside, I would much prefer that the Chargers franchise QB stop taking on opposing LBs and defensive lineman like he's prime Lorenzo Neal:

Again, I understand that this is popular amongst the offensive linemen and defensive players, but this would keep me up at night if I were Jim Harbaugh or Joe Hortiz.

Please, Justin, less of that and more of these perfectly thrown balls in the corner of the end zone:

I do think it's time to adjust my own priors and start thinking of Herbert as a duel-threat QB. It felt almost Eagles-esque how the legs of Herbert hovered above everything that was happening when the Chargers were on the field.

Third and short? Time to worry about whatever the Chargers version of the "tush push" is.

Play breaks down? Don't worry, Justin will just bulldoze through somebody to turn it into a positive one.

That being said, duel-threat QBs are usually threatening with their legs because they need to make life easier for when they drop back in the pocket. For many of them, it is much safer to try and run for a few yards then risk making a bad decision and putting the ball in the air. It's a conservative approach because you don't trust the QB to do it with their arm consistently without a diversion of some sort.

There's almost no reason to think of Justin Herbert like that, except...he's throwing more interceptions, and specifically pick-sixes, than he ever has before in his career. So, maybe Harbaugh and Greg Roman think they needs to simplify things by adding the running element? Or maybe Herbert is making more bad decisions because he keeps getting his bell rung? 

Or maybe this is a short-term band-aid for the usual (very injured) running game of the Chargers and the interception numbers are an aberration caused by tip balls and the like. There's no good way to figure that out right now, but these are all things to keep an eye on going forward.
