In case repeated blood samples are required at short intervals, a maximum of 0.6 ml/kg/day or 1.0% of an animal's total blood volume can be removed every 24 hours. The estimated blood volume in adult animals is 55 to 70 ml/kg body weight.
Four special teams units exist: 1  The group of players that handles punts, kickoffs, and punt returns. 2  The unit that handles field goal and extra point attempts. 3  The group that takes care of kickoff returns. 4  The unit that attempts to block field goal and extra point attempts.
It's also useful when a metric can isolate a unit on the field, like offense, defense and special teams. However, Yards Per Point does not do this well. For offensive Yards Per Point, defense and special teams play a crucial role in this metric. First, these units can score points. These scores lower Yards Per Point since no offensive yards are gained on these scoring plays. This assumes that return yards are not included in Yards Per Point, the method Chou used in his talk. Second, the defense and special teams affect field position.
