Rashad Johnson cannot play SS. All reports, confirmed by your eyes if you've watched any games, is that he is built like a corner_very light.
Delmas is much more like Roy (and Hamlin) with his tackling style. If he doesn't blow you up, he will either bounce off, eat turf or injure himself. NONE of the safeties in this draft are as money in eliminating RAC than Chung is. Don't know about anyone else but I am sick and tired of all the frikkin missed tackles & bounce offs.
Chung not only hits hard, he wraps up, he is the best, most consistent form tackler available. He is a playmaker and his role was more like a rover at Oregon, emphasis on stopping the run. But his athleticism & speed, not to mention the most important factor_HIS INTANGIBLES (leadership, character, football IQ, work ethic, instincts & intensity)_will allow him to improve in coverage.
And if people are going to knock Chung's 4.49, then why the love for Delmas' 4.53?
