I know "frame" is a hidden. Anyone know of others ? I've seen some low rated players really play lights out and vise versa.

frame???

Limits weight gain/loss when changing positions. Relatively new update.

Can you have a player just gain weight at his position?

Only if u change him from say a DE to DT. He ll ease up to around 300

So there aren't really any 320lb DT's ?

No , you would have to make them RT.

No quite yet. Upon discussion of a players "frame" the idea of setting a desired goal for each player was tossed around . As speed is tied to weight , this application has to be thought out to some degree before applying .

The old model had players gaining and losing over 100 pounds very quickly and with no limits. The current has limits and the futures ideas will be more of what you spoke of .
