Thanks for the feedback everyone!
I liked the skills pack we used because it was easy, and people who needed to build their team that morning could do it quickly.
The system I mentioned in my earlier PM borrowed liberally from the Spike Magazine Blood Bowl Tournament rules, which happened to come up on a google search I did. It was a little more detailed, with 2 tiers of Skills and different numbers of points depending on the team you play (so for example, Undead teams would get 9 points, whereas Halflings would get 17).

I didn't end up using it for 2 reasons. One is that it seemed a bit complicated for a casual, small event; the other is that Blood Bowl is inherently unbalanced, I have learned, and rules that look to correct that seem to go against the nature of the game.
But I am willing to consider some changes for next year, of course, and am open to suggestions!
Maybe only allowing specific skills to be taken by 2 members of the team? (I liberally bought Block for my Undead, mostly because it looked useful and I figured it would be easy to remember if everyone got the same thing, but I can see how it would be tough to play against)
The NAF has some examples for team building listed here which could be useful:
