I can understand Jacko needing to leave in search of fulfilling a career ambition to play in the Football league, but I would imagine the extra money would have only been a small part in the deciding factor. £200 per week extra would only be about £10,000 per year, whereas as successful testamonial against a top Premiership club in about 18 months would have yeilded £50,000 +.
Benno on the other hand has been a bit mercenary. I fully expect a player of his quality to comfortably play in Div 2 or 3, as does Jimmy Bullard. A couple of outstanding seasons playing for Fleet (probably as their best player) would showcase his talents to all league scouts, whereas he is likely to find he is only one of many League standard players at D&R, and his star qualities may not shine so brightly.
The same applies to Francis. Whilst it can be argued that he only played 8 games for a season's pay, he did get the injury playing for the Fleet. Any employee would expect to get paid if off sick because of an injury received at work. Francis is no different. However, Benno DID show star quaility and consistency all through a long, tough Conference season, whilst Francis is still (to a degree) unproven at this level. A lot of the games he did play were against poor, relegation haunted sides, not Yeovil, Morcambe, Doncaster or D&R, so I feel it would be in his best interest to get a full season in the Conference behind him to demonstrate to the world he is good enough to play at a higher level.
Notwithstanding all the above I sincerely hope Benno, Duke and Jacko do fulfil their ambitions and go on to play in Division 3.
