Bob, whilst I might agree with your sentiment about shirt numbers, it wouldn't matter to me personally, I'm not so sure that it applies to everyone even professional players.
Numbers rightly or wrongly, do have significance beyond simple playing positions especially the key ones IMO. For example, when there was a debate about Ratchford at FB the consensus seemed to be that TS first choice at FB was Russell as he had the No 1 shirt although admittedly it didn't seem to bother Ratchford the year before when he displaced Hodgson.
Apart from affording rank, for example your in the first 11, 13, 17 etc players can be superstitious about numbers and often a certain number is allocated to the team's star performer which might be a confidence boost or a burden although this usually applies more to football, United's 7 being a prime example.
All in all it probably as simple as it should be
