With pro boxing record 1-6 and having 6 lost fights via stoppage being 23 y.o my best career advice might be to apply for burger flipper job and there isn't meaning to insult someone at all but real life.I know, both are too old.
While old guy most likely does have some work exp under belt etc.
Young lad will be cheap " bag " not a journeyman....
Due his record details and ranking.....
Old guy was legs are done before fight had been signed up IMHO.
