I think you're missing the point. I don't care about the hits. Anyone can get hurt on any hit. I don't blame Tua for that. He was drilled, no doubt.
I care about many of the attributes that Herbert has that do not exist with Tua. If you watch Herbert throw on the run, it's beautiful. Rolling to his right, he puts touch on the ball throwing it 30+ yards and hitting his man on the run. Rolling to his left, he squares his shoulders and throws darts 20 yards downfield, again hitting his man crossing. He uses the pocket incredibly as well. He's as calm as I've seen a kid with his experience in a long time. A great example from last week when they were down 2 scores late in the third, they went for it on 4th. No panic, he scanned the field and threw a rope to the sideline for a first down. He's special.
Again, I don't care about anything other than the fact that we blew the pick. There is no way anyone looked at the skillset, intangibles, smarts, etc of these two and picked Tua. Oh, wait....
