Some of you guys are here most of the day, yet wait for this old bastard to come home from working and post the game thread. It would be helpful if the handful of regulars could post it and give me one less on my to do list of Tigers and Lions team notes, Musician's Birthdays, etc.
I won't be around until late Wednesday so if you want a game thread tomorrow, then one of you will have to get off your seat and post it.
