It's insane how some basic features just "disapeared" over the years.
After all these years I still think that 2k10 (I believe is the right year) was the most realistic hockey game I've played (the most fun being NHL Hitz Pro from 2004).
2k10 had roster sharing, more fun prospect development (that I recall), better trade platform, easier to navigate menus, etc. etc. The gameplay was a little weird at time (ie deking was kinda random), but it was just the begining of using the left joystick to control the player's stick so I can excuse that.
Also, you could control multiple teams in dynasty mode, and the simulation was FAST. It was really easy and fun to set up an evening of 2k10 gaming and do some dynasties with friends and play each other's teams.
