Wrestlers are proficient at taking their opponent to the ground and putting him on his back- not so much achieving the mounted position. Submissions pose a problem because they're not used in wrestling, and as a result, most wrestlers have never practiced them before.

Theres nothing wrong with a ground and pound style, its the fact that wrestlers are so good at taking their opponents down AND keeping them down (you get points for escapes in wrestling competitions). A common submission for example is the armbar. If done improperly, you'll lose you position and the submission. In this case if you're not particularly good at it, its a safer option to stay where you are and pound.
