Universally Challenged XI - a selection of the worst Test cricketers ever (minimum 10 tests):

Noel McGregor (right-hand bat & captain; 25 tests for New Zealand between 1955 and 1965, 892 runs @ 19.82 with one century)
C.S. Nayudu (right-hand bat & right arm leg break and googly bowler; 11 tests for India between 1934 and 1952, 147 runs @ 9.18 and 2 wickets @ 179.50)

By necessity rather than intention, this team is made up entirely of players from the early stages of their countries life as a Test nation. No batsmen with an average over 20 and no frontline bowlers with an average under 75 are included. Pretty impressive! A few other frontline batsmen have worse Test batting averages than Noel McGregor who did make a Test century, but they all have considerably better first class records than the Kiwi who achieved very mediocre results in both Tests and FCC. With a little more luck, I would imagine these players (including Neil Fairbrother, Arthur Jones and Saleem Elahi) may have had the ability to comfortably outperform McGregor. Also, Rubel Hussain has a Test 5for but a bowling average of over 75 in Tests and over 60 in First class cricket is absolutely atrocious for a frontline bowler. A few of the other bowlers actually have decent first class records but I would imagine the standard of First Class cricket in those peripheral stages of their countries existence as a Test nation was well short of what it would later become.
The combined batting average of this team is 136.26 and the average bowling average of the 5 frontline bowlers is 113.71, so in theory this team would have to bat 8.34 times to match the first innings score of a typical Test nation!
