Why is Lebron James in such a 'funk'? (ie. missing all his shots etc..)?

Its because Dan Gilbert cursed him. Go back and read that letter he wrote after Lebron's 'decision'. Unfortunately if you put a curse on someone, it never goes well for yourself also. Look at Cleveland... The only way for the Heat to have a chance to beat the Mavs now is for Lebron to get normal again. That means repent, stop doing that yoga, receive and follow Jesus Christ, and, ask Jesus to break the curse. (or just break the curse in Jesus name but only after receiving Jesus.) It doesn't take a minute and its free!
