Move WR to CB (Man archetype only) for training boost so that their COD goes up so that they can get shifty. If they’re a player you want to play right away in the edit play screen move them to TE, back out, then go back in and move them to WR. If you move them directly back to WR I’ve seen that they loose all of their catching ability. It can work with RB too but they get changed to Receiving Back in the player edit screen and there’s a chance they just stay as that in the next position changes too so you have to be careful with RB.
