No. 11 is a term in Cricket. It stands for the batsman who comes last in the order. Generally, the most incompetent batsman in the team.
Note: No. 1 & 2 are called the openers. 3, 4, 5 & 6 form the rest of the batting order. Some teams have an all-rounder at 6 or 7 and then the bowlers follow and complete the order 8,9,10 and 11. A competent batsman occupies a spot in top 6 atleast, if not in top 4.
Now, with the basics aside, the point here is if you send a qualified and competent batsman lower down the order, often, he starts playing like he belongs there. If he’s doing it consistently, he transforms into this incompetent batsman over time.
It is amazingly similar to the job that you perform. Even if you’re competent, if the job is of lesser cadre, you start fitting yourself to that job and ultimately achieve success in doing so. Finally, stay there all your life.
There are many people at fault here, but the prime one is you yourself.
Do not under-estimate yourself. Fight for a position in the top-order. You might be better than you think.
(No offense to bowlers; Just used batting to fit the context here.)
