Training camp is a time of transition for players and teams. Often times that includes a lot of discussion about where players are in terms of their weight. Tom Cable likes his linemen big. And right now the left side of his line is considerably big.
Donald Penn is rehabbing a foot injury, so in his place is the 6-8 top pick Kolton Miller. When he was drafted, he was just over 300 pounds. That’s a lot for most humans, but at his extreme height, and playing the left tackle spot, that’s a bit light.
