Bengals Rookie WR John Ross on DeSean Jackson's Speed: 'Child Please'

Cincinnati Bengals wide receiver John Ross isn't impressed with DeSean Jackson's speed.

For the record, Jackson's 40 time at the 2008 combine was 4.35.

It's not the first time the former Washington Huskies stud has flaunted his quickness. Last month, he challenged Usain Bolt to a race.

Ross also deleted his original tweet.
