Dinged Corners issued a challenge to find some "fierce foreheads". I went through my recently-acquired Collectors Choice SE cards because I knew it had some great photography.
Here's a classic "grrr" face from Grrrreg Maddux. He looks a bit like Mark Teixeira in this picture.
Darren Lewis grits his forehead, or just tries to avoid getting sand in his eye.
While scouting for foreheads, I saw some interesting writing on the bill of LaTroy Hawkins's cap. If you look closely (you may have to click on the picture) it says "Hawk Top Dawg 13".
