Assuming your numbers are correct, the last time we had a head coach with a winning record would be last year. You are saying Gailey's Win/Loss record is 25-26. Well if you subtract the 4-12 record from last year, this means Gailey's W/L record was 21-14 when he was hired. So technically, 2010 was the last time Buffalo had a coach with a winning record.
