Thanksgiving Football by BarkerC

The Detroit Lions have been playing on Thanksgiving since 1934 when they "invented" the gimmick for marketing purposes. What previously undefeated team did the one-loss Lions defeat that day en route to winning the NFL's Western Division?

But, Thanksgiving football has its origins in college football. On Thanksgiving Day 1898, the University of Michigan defeated what Western Conference rival 12-11 to become "Champions of the West" and inspired Louis Elbel to write "The Victors"

For thirteen straight seasons, beginning in 1951, the Lions perpetually faced what longtime NFL rival on Thanksgiving Day at Detroit's Briggs/Tiger Stadium?

In 1966, the Dallas Cowboys played their first Thanksgiving game (allegedly on an NFL guarantee that they would host them in perpetuity), drawing over 80,000 to the Cotton Bowl to see the Cowboys down this Eastern Conference foe who had lost to the Green Bay Packers in the NFL championship game the previous year.

For two years in the 1970s, this team, coached by Don Coryell, hosted the Thanksgiving game instead of the Cowboys (the Cowboys hosted this team in the 1976 game).

The AFL also hosted Thanksgiving Day games. In 1964 and 1965, what two teams met on Thanksgiving and then again in the League's championship games in both seasons?

In the 1989 Thanksgiving Game in Dallas, there were allegations that this team's coaching staff put a $200 bounty on Cowboys kicker Luis Zendejas, thus earning the name "Bounty Bowl".

It's 1993, it has unexpectedly snowed in Dallas. Miami's Pete Stoyanovich attempts a game winning 40-yard field goal that will be blocked by the Cowboys. Everything looks great until what Cowboys defensive lineman touches the ball, making it a live ball, allowing Miami to recover and kick the game winning field goal?

In 1998, what Steelers' captain (and future Pro Football Hall of Famer) allegedly attempts to call both heads and tails while the coin is in the air to start overtime, allowing said captain's hometown Lions to win the toss and kick a game winning field goal.

In 2011, what two coaches met on Thanksgiving Day in an interconference prime time showdown, then met again in Super Bowl XLVII in New Orleans the following season? (whoops!) (edited at 12:42 pm, November 25, 2015 (EST))

In the 2012 primetime game, what Jets' quarterback ran into his own offensive lineman, causing a gluteal turnover, which was returned for a touchdown by the Patriots?

The halftime shows at the Detroit and Dallas games are also fundraisers/awareness builders for two major American charity organizations. Name either of the charities that are the presenters of the halftime shows, this year featuring Big Sean in Detroit and Luke Bryan in Dallas.
