On the first part, probably. On the second part, a big NO. https://www.profootballfocus.com/news/pro-2019-free-agency-profile-bradley-roby In coverage, he was rated 102nd (among 131 qualifying corners). Kareem was ranked 14th or 16th, depending on the metrics used. https://www.profootballfocus.com/news/pro-2019-free-agency-profile-kareem-jackson KJax was definitely much better in coverage. Also, KJax was rated 2nd in run support; Roby can't touched that. In that ranking, KJax was rated as the 5th best CB overall. In the most current ranking, he was bumped up a notch. https://www.profootballfocus.com/news/pro-the-top-101-players-from-the-2018-nfl-season The Broncos front 7 is arguably the equivalence as that of the Texans. The one place that was in Roby's favor is that the Broncos faced better QBs overall - and that could make a difference. It's hard to quantify that so I won't even try. Another factor is all the injuries that the Broncos had overall; which put more burden on the remaining players, including Roby. So there's also that. ...... In the meantime , if we look at the QBs the Texans will face in 2019; Roby will have to improve a heck of a lot or it could be a nightmarish season, I'm afraid. Hopefully the Texans improve as a whole as well; and that could help the defense.
