For example: I have
Mike Jenner in HOF. The dude is mashing up the minors. If you get it all up in N00b heads that its ok to put your studs into the majors they will promote guys like Jenner into the Majors with a 58 in Durability and think that he will be fine...
Some guys who start with an 85 in Durability and 70's projected to high 80's low 90's and will play everyday at their position that is fine.
Even with Vargas... I would rather of had him play at SS and decline into 3B or something else rather than never play SS. You will pay less for him, and have him put up better numbers. You could easily have picked up a good player to reproduce 70's across the board for a fraction of the price that Vargas will cost you in long term free agency fees.
If you won the WS... it would have been worth it... but you didn't and now Vargas is more expensive in the long run, and somewhat less effective than he could have been.
