Not really USAR - a couple of years ago AAC (Adam Ashley-Cooper) took an intercept on the 22 and was run down by Robbie Fruen who had to turn and chase. AAC (Adam Ashley-Cooper) was caught before halfway. I know Fruen is fast but when a player has to turn and chase if you have even good speed you should be able to make 10 metres on him before he gets up and going. It highlighted to the top end pace that AAC (Adam Ashley-Cooper) doesn't have. Off the mark yes, outright pace - no.
His acceleration that he uses dozens of times a match is far > his top end speed he gets to use 2-3 times a year.
You're also citing one example in a sport where players regularly carry minor knee/ankle/hamstring/etc which could have a huge impact on top end speed. AAC (Adam Ashley-Cooper) may not be the fastest guy on the pitch but comparing his speed to Mike Harris is just madness.
