I agree with you on this. Same thing with big slower wrs, should be able to move them to TE.
The other thing that peaves me is strength and speed ratings changing. Example i tried moving my undersized, DT to DE, when i did i noticed his strength droppped from an 84 to somewhere in the low 70s. Um im sorry but strength is strength, same with speed, agility, acccel, etc. The only thing that should change prior to training, during the position change week is awareness, and it should be based on similarities in the position.
Example, there would be a bigger change in awareness going from wr to qb, as opposed to a smaller change in going from DT to DE.
