That's an excellent point about scouting, and one I've harped on since day one. I have no idea if it was "realistic" to add players to your team that way, but boy was it FUN!
When FIFA 11 first came out, I hated it because of the tackling issue and all of the good stuff they gutted out of MM from FIFA 10. FIFA 10's career mode actually was a pretty good framework, it was just horribly glitch-ridden and it lacked any sort of polish or detail. FIFA 11's career mode is much better to look at, but you really are left pretty helpless trying to improve through transfers, and that player list sorting menu is a nightmare to navigate!
I did grow to like FIFA 11 over time (lots of improvements in the aerial game/overall polish), but the proposed changes to physics are pretty exciting. It's not a lot of to watch my players get absolutely murdered in a heap, and then wait as no call is made and the perpetrator comes and steals the ball from me. Also, don't think I've ever seen a red card called in possibly 100+ games.
