Do you not watch the Path to the draft or NFL total access?
Seriously because thats almost all they talk about is players moving to different spots and being able to play those. CBs that are to slow get moved to saftey. Safteys that are to slow get moved to LB. LBs get moved to saftey and DE. DEs will make the change to LB or DT. DTs in 3-4 will be DEs. Try making half of these changes in NCAA and see what happens to their stats.
The move from WR to DE would be a tough thing and not to many players can pull it off. That was one of the best examples of a player from no were moving to a spot you wouldnt think possible. Football is all about finding the spot where you play best and where your team needs you to play. For Jamal he changed to DE and is still a starter in the NFL which is more then most people can say.
Heck, there are QBs and HBs that played LB in highschool that picked one in college and went with it. If I get a offensive player and I see he would be better suited on my team to play defense then I should be able to move him without the 10 point speed dock. If I see my RT is to weak to play T on my line I should be able to move him to TE without see his stats get jacked up.
If they want to make the game sim then they need to let us do what we want with our players we get without killing what they physically are. I would even say as much to dock awareness and play recongiton because each position has its own view of the game and it takes time to adjust mentaly to it but physically if your fast you are fast if your strong you are strong. Changing where you play on your team offically doesnt change that period.
