Yes, I've done it many a time (eg Harmison in his 3rd, 4th and 5th VB Series games 2 winters ago).
If I truly believed Gough wouldn't be around in 2007 I'd be the first to say "there's no point picking him in the side". I credited Caddick, Knight, Stewart and Hussain for retiring when they did - so many people acted surprised, not realising that the next World Cup is all that matters in ODIs.
But Gough has publicly stated his aim is to be around for that World Cup - presumably principally based on his disappointment at missing the last.
37 isn't that old any more (well, it never really has been), even for a bowler (well, a good one anyway). Personally, I'm all for giving him the chance.
Of course, like anyone else, if his performances really do drop he should be left-out.
But as it is, a "drop in performance" from Harmison right now would probably be being smashed for 10 or 11 games. For Goughie we've heard cries already, from countless quarters, for his axing, due to 2 bad games.
2 bad games! Just TWO. That, to me, is very harsh, and purely because of the perennial, never-stopping generalisation in sport about older players.
