Oh god...I'm usually a really good sport. Blood Bowl has succeeded, once, at making me get so pissed off that I threw dice. Sorry for the (indirect, bounced off the wall) dice to the face, Shane!
The passing template is needed to determine who can intercept, if you are being competitive about it. In a 'friendly' game, you can just wing it.
Blood Bowl is fun, and I wish we played more of it. The league a few years ago was going strong for a while, but kinda fell apart. Depending on how the OFCC schedule is this year, I kinda want to do either Rat City Rumble (if they are still going) or SPIKE this coming year.
I think putting together and/or converting your team is a really fun part of it. I made a Norse team, the Isefjord Pillagers, from GW marauder bits and some Reaper minis.
If you want a second team to have friends play, Orcs is always a good choice. Humans get a bit of everything too (that's I'm sure why Orcs v Humans are the teams in the old retail box).
Depending on the version of the computer game you've been playing, you may or may not be familiar with the latest rules that most of the tourneys use, the CRP, along with the extra teams.
With the release of a bunch of LotR and Hobbit sets, I may have to look into putting together my custom Lego High Elves again...
Let me know if you get stuff together, I'd love to play. I have a team and lots of dice; just no pitch.
