Bengals rookie Ja'Marr Chase is giving an interesting explanation for his preseason blunders ... saying he's been dropping so many passes because the NFL balls don't have white stripes.
It's safe to say the ex-LSU star has stumbled out the gate to start his pro career ... dropping an eye-opening amount of passes after barely having any issues in college.
Chase -- who sat out the 2020 NCAA season to prepare for the draft -- opened up on his struggles this week ... and while he says he's not making any excuses for his performance, he explains the differences he's had to face so far as a pro.
"I don't want to blame it on me sitting on my butt the whole year, but it probably had something to do with it, of course," the #5 overall pick in the draft told Bengals.com.
"There's a bigger ball adjustment, so I don't want to make excuses but I've just got to be a pro and make the catch."
Chase describes other differences with the NFL ball that could be impacting his game -- the white stripes.
