ok to answer your guys questions, well for it to work you first need to wait until they get released from the team before you can retire them.
@Sev your player will be at that level when the season ends, but for the team right now you need to retire your players then build them on Day 41, which is Saturday for all of us (Deft sed he will take the season off for school so saturday would be suffice)
@Shura well i think for now, what type of work you want to do? you want to pass, run, catch, tackle, punt, or block?
Here's my own opinionated view of Easy to hard
Easy: OG, OT, C, P, K
Medium: DE, DT, LB, CB, FS, SS, FB, TE?
Hard: WR, HB, QB, TE?
Now, I have built all different types of players and to be honest many are headaches and from others I will tell you from a honest perspective, many take on specialties so this is the approach I am going to take to next season, I will explain more in the IRC to this approach, if you guys see me in there, join #GLB room
