Buffalo Bills fans have managed to get caught up in what can only be described as Rex Ryan fever.
Ryan was the head coach of the New York Jets from 2009 to 2014, and in that time Jets fans fell in and out of love with the maverick coach.
The former Baltimore Ravens offensive coordinator enjoyed a successful start to his coaching career in the Big Apple, but ultimately things ended on a sour note.
Terrible end in NY
The Jets made the playoffs in both 2009 and 2010 and went deep in the playoffs, making the AFC Championship Game in both years.
But there was no second Super Bowl win for the Jets, and four barren years of not making the playoffs followed for Gang Green.
Following a 4-12 poor campaign last year, Ryan parted ways with the Jets and somehow landed himself another head coaching gig - this time at the Buffalo Bills.
And it seems that this new opportunity in Buffalo has reinvigorated Ryan to the extent that he is exciting the whole of Bills nation ahead of the upcoming campaign.
Reports on Monday even reveal that the Bills have set a franchise record for season ticket sales, with more than 57,500 sold so far.
Granted, it's not just the arrival of Ryan that has increased the season ticket sales by 10,000 from 2014, with the arrival of star running back LeSean McCoy also likely to be behind the surge in support.
But most importantly the noises coming out of the mouth of Ryan are positive and optimistic. And for a fanbase that hasn't made the playoffs this century, it's as refreshing as it is inspiring.
"Bills Season Ticket Members passionately support this team year after year and are the most loyal fans in the National Football League. We truly thank them for their commitment to this franchise," Bills owner Terry Pegula explained on Monday.
"Like our fans, we are looking forward to a great 2015 season with our Head Coach Rex Ryan, the coaching staff, the players and the entire organization."
There is no doubt that Ryan has what it takes to inspire players to believe in themselves and inspire fans to believe in their team. He did that to perfection in New York, but ultimately his persona has an expiry date.
The Bills will have to achieve their goal of making the playoffs this season or else Ryan's second honeymoon period in the NFL will come to another screeching halt.
Will RexMania last in Buffalo or will it die off like it did in New York? Let us know below.
