Game-used NFL football - get signed?

[BVC]

I have a kicking ball used in last year's NFC Championship Game between the Seahawks and 49'ers. I have it photo-matched through the 3rd quarter, including Doug Baldwin's 69-yd kick-off return. Given the Baldwin return and two Hauschka field goals, should I get it signed by Hauschka, Baldwin, both or neither? Both are available for signings this month. I also have it photo-matched to a 49'er punt return fumble, a Dawson field goal and a 49'er kick-off return (James), but don't want to cover it with enemy signatures . Any ideas are appreciated.

Moderators - is there any way to remove useless threads?

My apologies.
