This would be correct if he had been any good for us. He was any expensive bench warmer at best, and Upson has done way more in 5 games than Dobbie did in half a season.
I agree that Upson has been great, but you're not going to convince me that we were right to let Dobbie go to a play-off rival however much bench warming he was doing. If he scores a play-off final winner, after the embarrassment of the Murray saga, I'll need a long lie down.
