I love everything about this.

Apart from that the dwarf coach needs investigating for match fixing - it probably says more about me than your post that I was almost apoplectic with disbelief when I saw the words 'dwarfs' and 'loose cage' in the same paragraph. The acknowledged tactic is a tight cage and a 20 turn amble downfield culminating in your blitzer stepping on the last surviving Slaven's spine as he walks in the score.
Second edition blood bowl was probably the first GW game (perhaps along with Space Hulk) that my fiends and I could understand well enough to play properly and has a very special place in my heart too. That and the amazing Pete Knifton artwork bring back a lot of memories of gaming afternoons with friends. Although there is no denying that 3rd edition onwards is a better game as it was really hard for agility team to compete in the inevitable mid-field melee. And if you played to '3 scores wins' it could take longer than a game of WHFB!
If there's one rule that you should add from the compendium its being able to use agility (in a defensive way) in a block. It really allowed the agility teams to compete. Even without the nefarious skaven match-fixing!
