Another NFL game was determined due to a questionable call last night, once again bringing up a discussion that Patriots coach Bill Belichick has been at the forefront of for a while.  Should NFL coaches be able to challenge any play, and not just two (or three if they win both) per game?  It could potentially make games longer and open up other issues, but the NFL always says the big point is to get things right.  What do you think, would you be open to the idea of coaches being able to check a play at any point during a game?
