BigSlick proposes that at season's end, the total of Jon Lester's ERA + Clay Buchholz's ERA will be under 6.50. MrNE takes the over on that, with high stakes added:
At the end of the season whoever is right gets to pic the other's avatar for a month.
As a result of MrNE's bet, the over/under line moved to 7.00, at which point ghostoffoxx promptly took the over. (stakes unknown)
Which brings us to right now. The line has moved again. The over/under is now 7.25. Someone keep the betting alive.
