No they didn't, you couldn't stab with them, just throw them.
Why does everybody bring up the freaking animations? Of course it's relatively easy to do, that's not the problem.
You mentioned how they're near useless close quarters, I agree, that should be in the game, but I don't know how could it be made to work in a first-person game that you can't stab/slash somebody who's really right next to you, not to mention, how would you make it clear with the player when is he in reach.
Just thinking this over made me think of a really uncomfortable system, ironing these out would take way too much time and resources, they could be spending on something else...
Hammers and axes are on poles as well you know, and TES has both. They have a range max and a range min just like spears. The fix? Bethesda just ignores it. Even massive hammers are just as effective at point blank as they are at 3 feet. Just do the same thing for a spear.
And there is already a thrusting move for claymores and swords, it wouldn't be a stretch to just modify and use it for spears. Hell even hammers have a thrusting animation which doesn't even make sense. (Not to mention that, if you look at the hammer thrusting animation, it would be perfect for a spear right out of the box.)
So...
1. Animations - no big deal. They already have most of them, and it would be easy to tweak or crank out a couple more. Non issue.
2. Balance - no big deal. The spears could be balanced for damage and range just like any claymore or war hammer.
3. Fighting style - no big deal. The spears could be swung or thrusted just like we swing the axes and just like we thrust the hammers. You can block and bash just like a staff.
