Just seen this, sorry if it sounds offensive but you need to take off your rose coloured specs here mate. The MLS is a graveyard where old pro's careers go to die.
I'm not trying to be offensive, I watched a good bit of MLS when I was in the States (Orlando City had fooking Kaka playing for them) and I watched a lot of it last year when I was in Poland (they show a lot of MLS over there for some reason)
Some games were good, quick tempo, goals at either end, but I could not justify saying that the standard is the same as the championship, because it's not, maybe lower end of the Championship, but the games just have a slower pace, they seem more relaxed in the MLS. Im not saying this to wind you up, theres a good reason that so many pro's head out there before retirement, it's a warmer climate and less physical league than anything in the UK.
