Pick'em Helper од Clint Cecil

Each open game gets a drag handle and ▲▼ buttons. The table stays in
confidence order: the top game gets the most points. When you move a game,
every open game gets a value by its place in the table. The extension sets
Yahoo's own confidence drop-downs, so you still click Save Picks. Games
that have kicked off keep their value and can't be moved. If you pick a value
from a drop-down by hand, that row moves to its place.

• Group row under Favored/Spread/Underdog: the share of the group on the
  most-picked team for each game. Hover a cell for both teams' counts, average
  confidence, and the spread-implied win probability.
• Contrarian marks: an orange outline on picks that 30% or less of the
  group made.
• What-if columns after Yahoo's Points column (hover a header for how it
  is worked out):
• Max: current points plus every remaining pick right.
• Status: Clinched / Alive / Tie only / Out. It checks every
  combination of remaining results.
• Needs: with 3+ games undecided, the results the member must get in
  every scenario where they win. With 2 or fewer (Sunday and Monday night),
  every way they can still win, including what rivals must have picked on
  hidden games, e.g. Chi wins · Avery picked Phi or
  LAR and Chi win · Avery's 12 pick loses ("12 pick" is the pick they
  put 12 confidence points on). The cell shows 3 lines; hover for the rest.
• Win %: 20,000 simulations that use the spread for each game. It is
  hidden while more than 3 games have hidden picks.

Yahoo hides other members' picks until each game kicks off. The extension
works out the points on a hidden pick from the confidence values that
member has not used. It can't know the team. Status treats hidden picks as
a best case for the member it judges and a worst case for everyone else.
