While TH's squad is strong on experience, I feel it is limited as to it's long term benefits to NZ Cricket. To me there is no point in selecting perenial 2nd stringers unless there are no other options available, or established senior players unless there is a specific benefit to be had.
Such players would include the likes of Sinclair, Wiseman, Walmsley and to a lesser extent Jones & Bell. Likewise the selections of McCullum, Mills & Adams would be wasted for a Limited Overs match / series as they are established ODI squad / players with over 2 dozen caps each. The only times I would be using the likes of these 8 players (other than rehab) would primarily to give the side some experience to balance an influx of Acadamy / fringe players, who would be the main focus of the development.
From what I can see NZ has a number of options across the board, although the bowling appears a little thin, particularly for anything other than fast/med:
Jones, Bell, Papps, McIntosh, J Marshall, Horsley, Cumming, Ingram = Openers;
H Marshall, Fulton, Ryder, N Parlane, Orchard, Nichol, Taylor, Broom = mid order;
Franklin, Adams, Canning, M Walker, Yovich, Sheed, Woodcock, Gillespie, B Walker = lower order;
Patel, Wilson, Mills, Mason, G & H Shaw, J McMillan, M Hart, B Martin, Butler = Tail.
35 players with a spread of age, experience & prospects, with less than a dozen aged in their mid 20s or older. Some with established F/C careers, others less than a dozen F/C matches to their credit.
Current fringe include - Jones, Cumming, Adams (Test), Canning, M Walker, Mills, Mason, Butler; Retreads include - Bell, H Marshall, Franklin, B Walker, Wilson, M Hart; with the rest being prospects of various age & experience.
While some of these players have less than glorious previous selections to their credit, I am a firm believer that once these players have been identified via the Acadamy / training camps / prior selection, that they should not be returned to the domestic competition & forgotten / left to fend for themselves. These players should continue to be nurtured thru their early careers including 'A' Team selections to better prepare them for full internationals, and to address any form difficulties they need to address such as Franklin, Sinclair or Bell.
Similarly I believe that promising youngsters should be brought into the fold sooner rather than later, so at the very least they know they are being watched / groomed to be given their opportunity in the future. Too often IMO good talent is lost for want of encouragement or recognition.
Likewise if they are not lost then they could change / neglect the part of their game that had the potential to be developed. Eg NZ has a wealth of med / fast seamers - how many have dropped their pace or have changed their actions from banging the ball in to going across the top, or have not taken advantage of natural swing action etc?
