I haven't seen anything to suggest Randall is sheepish about tackling, which is why I think he should be a better tackler than TW. However, poor tackling isn't less of a liability if he is better in coverage. It is what it is regardless of coverage skills. Ultimately, his playing time will be determined by his coverage skills, not his tackling ability, assuming, of course he doesn't turn the other way and run away form ball carriers.
