Like I said, some teams generally feck up in the regular season...you have to factor in a lot of things, They were missing a Point Guard for one, until they traded for Bibby, as for the terrible chemistry in the team and everything else, we'd have to go back to 07/08, but my overall point still stands that Hawks team was strong, perhaps all they needed was a really good point guard (they traded for Bibby in February just before the playoffs)and a full season under Horfods belt(he was drafted that year), that was their last season under 500 until last season of course, I can see how they could've matched up to the Celtics in the playoffs though.
This could go on forever, we could go back in time and find examples of teams that have done feck all in the regular season in a relatively weaker conference and still ended up doing well in the playoffs(by their season standards), a fecked up reg. season in a weak conference doesn't necessarily mean the team is weak, it just means they had a fecked up season...... Now if the Hawks had taken the Celtics to a game 7 with a bunch scrubs(average players ), that'd have shocked me not with 5 solid players (2 all stars, who had a bad reg. season).
That's just playoff basketball,no real surprise there.
