By “specific” I am referring to the quality of sprint runs as a primary means of creating adaptation that contributes to the final product. The maximal weights portion of the training would be considered “general” in the sense that it is creating a general improvement in strength that will feed into the sprint training (starting strength, acceleration, general body integrity as mentioned by Lyle).
Your points on the MVP program are well taken, as they are not trying to get fancy with their weight program. It is what it is – a general means to an end. The sled work and hill work can bridge the gap between general strength and speed.
