If you want to use a dice for breaking tackles it's fine. But remember you are simulating the action therefore a tackle must be broken regardless of how it's done.

Also remember that there are many different ways of playing but when talking in football terms, the language is universal. The more we talk football, the more we dispense with the discussion of styles and what works best.

Play the game the way you like best. What's most important is that all elements are provided for in some way and not overlooked.
