He was posted missing in games against the taigs and did not have a CL goal. When he was at his peak, we were often in the CL. So it's 235 games and 138 goals, that's a goal every 153 minutes ( a goal every 2 and a half hours). That's a tidy return. But if we just do big games, in 19 Euro ties and at least 20 games against the filth (probably more) he got a total of 4 goals, that's a goal every 877 minutes or every 14 and a half hours. So if we exclude Champions League, Europa Cup and Filth games, he was a good club servant.
I liked Boyd. I'm of an older vintage. But let's remember, we are not Killie,. At Rangers you are judged on the marquee matches.
