Apparently he had too many WTF attempts/moments.
He has an amazing leg/distance, but had pretty subpar accuracy on midrange kicks. Give the longer extra points in the nfl, he was becoming somewhat of a liability. Pretty sure he even said that it was evolving into a mental thing, which is the death knell for a kicker. Hopefully he can get things straightened out (pun intended); with his range, my guess is he will get more chances.
