Are you talking about Brian Kelly having speed? Ummmmm....what speed? There was all this talk in the 2016 pre-season that Kelly was quick. It took less than 80 minutes in Round 1 against the Worms at Brookie to dispel that myth. At one point in that game he got put into the clear, 40 or 50 out, no one in front of him.....and from 10 metres back Semi Radradra had him before he'd gone 30 metres.
Brian Kelly isn't fast. He has a good sidestep and decent acceleration off the mark, but his top pace isn't fast at all. We saw that tonight when the Titans made a break and their 5/8 put in a kick for Anthony Don and Kelly to chase. Don and Josh Morris in particular left Kelly for dead, he simply couldn't keep up.
