I can't say that I'm disappointed that you didn't add a player. 
Prices always seem to get crazy before the playoffs. In an effort to beat Bullish Mentality a few season ago, I spent way too much on $200K+ guy (10751231) on the Saturday before the playoffs (even though I couldn't really afford him). My plan obviously didn't work...and it took me a season to recover from the damage:
Transfer 4/28/2012 19 Purchased from yigidospor for $ 853 700
Transfer 5/12/2012 19 Purchased from 10inch Vertical for $ 94 200
For every one time a guy successfully comes out of nowhere loads up at the end, defies the odds and promotes, there are 4 times where it blows up in the guys face. If you think about it, most of the time the championship comes down to 1-2 maybe 3 teams that were ahead of the pack all season. With HCA being as strong as it is in this game, it's tough to to do enough at the end to overcome a quality team's HCA.
I think the market did Calfson a favor by boxing him out :-)
