I'd like to see Gore traded or released. He doesn't need to spend what's left of a great career on this crappy team.
This is isn't what he signed up for when he joined the colts and no reason to make him suffer on a losing team if he can possibly join one with a chance at the playoffs.
If this season starts to go south quickly and Luck is out, I'd try to do him a favor and either trade him for a late round pick or release him so hopefully he can catch on with a contender.
No reason to spend what will be one of your last NFL seasons on a crappy team.
