I think you have a right to be pissed, unless these guys were called into emergency surgery or something. You make a commitment to make the draft and then you back out? You're not welcome next year.
Scheduling this year's draft was a major pain in the ###. We basically have our draft the Saturday before Labor Day Weekend each year. Well, now I've learned I have to put that on the calendar a year in advance. This year, all I heard from everyone was, "I'm out of town", "I've got a hockey game", "I can't do Saturdays", etc...Guys we do the same damn day every year, mark it down and don't freakin' schedule anything.
We ended up doing it on Friday night, but we had 5 owners drafting on-line with the rest in person. But even then, a few guys were a couple rounds late, so we had to call them on the phone for their first couple of picks.
Does it work? Sure, you can make it work. Is it a pain in the ###? Yes, it's a huge pain in the ###. I just want to sit back and drink my beer without worrying about who I have to call, or whether someone's internet connection dropped (which it did several times for one guy).
Our draft used to be about sitting around for a Saturday, drinking beer and talking football. Now, everyone's worried about some other crap. Is fantasy football life or death? No, but if you can't make the commitment one day out of 365, then I don't want you in the league.
