Reading some Players guides on the main site, I can't understand why anyone would put 'diving tackle' and 'shadowing' on the same player. On the one hand, if I want my player to dive tackle someone and fails, he cannot follow up with shadowing. And if I send my player to shadow someone instead, then at what point would I use the diving tackle skill? It seems to me that both skills serve the same purpose of countering dodging players but I don't see how having both skills is better than only one on a player. Somewhat akin to block and wrestle. Both counter 'both down' in a different way, but you can only use one or the other.
