bottom bracket lifespan

so how long should a campy record bottom bracket last? bike is a look 585, with campy record, compact 50/34 front. biker is 5'7 150 lbs. . this bracket has perhaps 9000 miles on it. lbs when i took the bike it for a tuneup felt a little play in the crank, called me to say they need to replace the bottom bracket. Any comments? Just seems to me something like that should last longer than a little more than a year, but maybe i am naive to these things.

Tell them to do nothing and that you'll check it out yourself.

All that's needed is to look at the spindle and cups. If they are smoothly and evenly worn with absolutely no pits then just rebuild with new ball bearings. A broken in bearing runs much smoother than when new. If pitted or unevenly worn it must be replaced. Then monitor regularly both adjustment and smoothness and overhaul more often.
