Sounds like he's not at Carlisle as a back-up to Norman and that Beech wants two, league-ready keepers to fight for the jersey over the coming season. I get the impression that he felt Collin's performances dropped in part because he had no one to really challenge him for the number 1 spot.
David Holdsworth then probably had a lot to do with Furman coming to the club, it was Holdsworth who brought him into Lincoln City from Gateshead whilst manager there. He's definitely in the "All I want to do is play football" camp, he was settled at both those clubs and could have stayed but decided on moves away each time once he was in and out of the team.
There's an interesting, extended interview with him on the D3D4 '30-minutes with....' series of
podcasts, which was recorded and broadcast just last month. Described Holdsworth as a "great guy who really looked after me"!
