Inside the Article:
At one point in time, Darius Slay was emerging as a solid cornerback for the Detroit Lions. That is until he was traded to the Philadelphia Eagles, where he is now a perennial Pro Bowl player, and headed to the Super Bowl. On Tuesday, Slay was asked about Matt Patricia, and he is clearly still fueled by disrespect from the former Detroit coach. “He basically just said, ‘You are not in that category yet'”, “At that time, I only had 1 Pro Bowl but now I'm at 5.” “I don’t wish bad on him, but as a man, me and him just don’t get along”

Why it Matters for Darius Slay
Since heading to the Eagles, Slay has been to the Pro Bowl in two out of three years, while Detroit has struggled at the cornerback position in a big way. After trading Slay, the Lions, who had Bob Quinn as their GM at the time, selected CB Jeff Okudah with the No. 3 overall pick. Okudah has left much to be desired during his time in the league as he has dealt with injuries and not performed at the level expected out of a Top 3 pick.
Bottom Line: Slay still is not a fan of Patricia
Despite time going by, it is pretty clear that Slay is still not a very big fan of Patricia, and to be completely honest, not many players who played for Patricia are a fan of his. Thanks to Patricia driving Slay out of Detroit, the Lions are still looking for a true No. 1 cornerback.
