Well he played 69 game for Preston at that level and I can't remember him getting skinned too often by the better players (Roofe etc) that we came up against last year. For me Buchanan's a must keep, as much for his experience and leadership qualities as anything else.
My main concern at the moment is further up the field. Revell is clearly a more than decent targetman but his signing is slightly reminiscent of when Hoofroyd brought in Clive Platt when we already had Bayo. For me Rico and Revell are too similar and the budget would have been better spent signing someone who offered something different (i.e. pace) in addition to signing a young and hungry back up/long term successor for Rico (Marquis).
If Page goes for a 4-4-2 with Revell and Rico up front and two traditional wingers then he'll be abandoning what made us so good last year: a fluid 4-2-3-1 with a dynamic front four and JJ bossing the midfield from deep. When we played 4-4-2 following Collins' arrival we started looking leaden and predictable and results suffered.
Before any of the 'happy clappies' pile in, I'll say that it's very early days and these concerns will probably prove to be completely unfounded. However, I still think it's a debate which is worth having, particularly when our long-term survival at this level is at stake.
This pretty much nails my thinking, too.
