No CLT20 but the heavy roller is back
Five things to watch out for during the 2013 county season

Teams from England and Wales will not participate in the Champions League in 2013. While few would dispute that the idea of the league is, in principle, attractive, the practicalities have rendered it far less appealing. The CLT20's owners - Cricket Australia, Cricket South Africa and the BCCI, who are the overwhelmingly dominant partners - were either unwilling or unable to compromise over the rules or the scheduling of the event, meaning that the county season had to be abbreviated or compacted in order to accommodate any involvement. It also grated counties that, despite the inconvenience of participating, they were forced to take part in an extra qualifying event for which there was no prize money. They were also allowed to field just two overseas players, while other teams were allowed four. In 2011, Mumbai Indians were even allowed to field five overseas players to "retain the integrity of the tournament".
After a three-year absence, the heavy roller will return to the County Championship. Without it, county cricket enjoyed plenty of low-scoring, fast-moving games. In terms of encouraging entertaining cricket, the move was a resounding success. But there was an increasing concern that the balance between bat and ball had veered too far towards the bowler and the domestic game was failing to provide adequate preparation for international cricket. With no heavy roller to flatten dents made by the new ball in the first session or two of games, bowlers were able to gain assistance throughout matches. The hope is that, with seamers provided a little less assistance this season, spin bowlers may have more of a role to play as games progress. If county cricket is purely about entertainment, that may be a regrettable decision. But in terms of mirroring conditions in international cricket, it probably makes sense to re-introduce the heavy roller.
While the movement of players between counties on loan was introduced in 2005, it is likely to become more common as a result of changes introduced this season. This year the loan system has been adapted so a player may be loaned for a specific competition while continuing to represent their original county in another format. Therefore, a player such as Paul Stirling, who is a key figure in Middlesex's limited-overs team but failed to play a single Championship match in 2012, will be able to continue to represent Middlesex in the shorter formats, but will also have the opportunity to gain first-class cricket with another club. The aim is to both aid players' development and reduce the gap between the richer clubs will large squads and the poorer, who have a smaller pool of players.
Over the last few years, the ECB has incentivised counties to field young, England-qualified players. Clubs are financially rewarded for including nine England-qualified players in each Championship and Yorkshire Bank 40 side, with the optimum payments being made if two of the players are aged under 22 and three more are under 26 on April 1 of that year. While the richer clubs can ignore such incentives, they are absolutely crucial for the smaller clubs. This, in turn, has seen more mature players - those over 26 - leave the game earlier than was the case in the past and some young players promoted before they are ready. While the aim is laudable, the concern is that the changes came in at the same time as tighter work permit regulations concerning the registration of overseas and non-England qualified players (such as Kolpak registrations), it has increased concerns that it may, in time, lead to a dilution in the quality of some county cricket, particularly towards the bottom of Division Two.
This season will be studded with updates on the negotiation of the England players' new central contracts. Suffice it to say that they are likely to receive very significant pay rises after it was revealed by Angus Porter, the chief executive of the Professional Cricketers' Association, that Australia's cricketers earn, on average, twice as much. Porter was quite right, too. While Michael Clarke, for example, earns around £1.3m a year from Cricket Australia endorsements and contracts, few of his counterparts in England reach half of that. The ECB's explanation that the cost of living in Australia was much higher than the UK has been met with derisive laughter.
