Tell me of a college QB who rushed for 1000 yards, and became a Pro pocket passer?
When it's in your DNA to run, you just run instinctively.
Murray didn't amass 1000 yards rushing in his senior year because he's a pocket passer. Besides: a 5'10" QB has a harder time than taller QBs seeing over the line. This is why the NFL standards want a 6'4" QB.
I'm not saying that Murray isn't accurate in the pocket. I'm saying that like Wilson, he often has a hard time finding passing lanes because he has a hard time seeing over the lines.
He will run because that's who he is. And as a result the risk factors of injury climb exponentially.
