I bought one right after the signing on Saturday for 2 reasons:
1) With the TO signing, the FO is at least showing more of a serious commitment to winning this year. I respect that and have longed for that, so I'll do my part in financially supporting the team.
2) It's TO on the BILLS!!! If it ends up only being one year, it'll still be worth it to me as a collectors item. Just cool to have.
