No way to justify that, Ingram ran a 4.62 40 at the combine, he doesn't have top end speed. Every scout/ananlyst shares the opinion that he's not a home run hitter, but he can get yards in chunks because he has good burst, he's hard to bring down, and he makes people miss in the hole.
Just because speed is over-effective in Madden doesn't justify a players speed being boosted to be a better "Madden Player". Colston isn't fast in comparison to other receivers and DB's, when he makes plays vertically he uses his frame 6'4", and leaping ability (ala Fitz) to box out the DB and attack the ball at it's highest point. He doesn't run past anyone, but he can get deep.
