For a club of our size and resources, deals longer than two years are generally too much of a risk.
When Norwood signed his last contract he was not even a guaranteed starter at National League level and was sometimes behind Andy Mangan in the pecking order. Given that we had the ambition of reaching Leagues Two and One in the near future, levels that Norwood had never played at before, it would have been too much of a risk to offer him a very long contract. We did not know how good he was, or how he would adapt to a higher level. We can't simply stockpile players on decent wages in the way Premier League clubs can.
Of course we would offer Norwood all the riches in the world now, but hindsight is 20-20.
The three year contracts offered to Kirby and Stockton were completely daft and were the brainchild of Jeremy Butler, which says it all.
