It is probably a tad churlish to point out the flaw in your well thought out post - it hardly has escaped your notice that Dundalk are currently top of the league and bookies favourties to regain the title.
You may also be aware that on the goalkeeping front Dundalk have conceded the least goals of any team and have the most clean sheets.
A specific statistic about Gary Rogers that you may not be aware of, is that he has 15 clean sheets in 22 league games - an almost incredible shut out rate of 68%.
