Buffalo Bills rookie QB Josh Allen ain't jawing back at Jalen Ramsey ... in fact, he's combating Jalen's trash talk with one of the nicest compliments you can give.
Just last week, Ramsey -- the stud corner for the Jacksonville Jaguars -- retweeted some video of Allen throwing at Bills rookie mini-camp and said, "That's a pick waiting to happen."
So, when we saw the 21-year-old at LAX, we asked if he took offense ...
"That's probably one of the best corners in the league," Allen said.
