Stringe game? Cheating?

In today tournament game my adversary scored 7 tries, each identical returning kick with the number 7. Strange thing is that the players alternating in that position had respectively (in speed, attack acceleration and penetration): the first one 34-44-39 the second 40-40-40, the third 43-43-41 versus my 15 who had 55 in speed, 53 in defensive acc e 55 in tackle (my 10 Was also 55 in speed and 40-44 in def acc & tackle).
I'm playing by about 2 months and I couldn't understand how this was possible.
He played a friendly Match before the game, saw that ma kicks go the opponent 7 and then this strange phenomenon that its numbers 7 were able to return unopposed 7 kicks even with stats largely inferior.

By the way, in anti case, my opinion si that the ability to play explorative friendly games to uncover opponent tactics it's a bug of the game.
Thanks in advance for any response.
In strategy and individual instructions, you can change rhythm and attack speed, that can increase the running speed (and decrease the ability with the ball).
There is also the match bonus that can double players' skills.
Thank you for your response ... But still thinking that the stats difference was too heavy to giustify 7 tries with no opposition.
Spend some big money, put your team on at least 50% or higher match bonus and take on a team with a much higher star rating than yours and see what happens. At 50% it looks like your team is on steroids, like i have really fast runners but then i played a guy who was over 45* rated and 2 levels higher than me, i was only 29* then, i paid the excessive $1.3million to put a 50% match bonus on my team, at 1st when the game started it seemed like it was playing at double speed. My guys ran circles around the other team, I scored my 2nd try within 20 counts..
