Well, theoretically we're still not clear of relegation! we're only 20 points ahead of the Falcons, with 5 rounds to go (25 points on offer...).
Realistically, I'd say that anyone from Bath down is at risk. What's different this season that with 5 rounds to go, the *bottom* club has already got 6 wins. If you look back through the history of the Premiership, there's only been 3 teams relegated having won 6 games in a season (Us, Saints twice, and Falcons most recently as 2012, with Leeds avoiding the drop in '02 because Rotherham's stadium wasn't up to standard), and only once has a team that's won 7 games gone down (Bristol in '03).
This season there's been a big "levelling" of the teams from 3rd down to 12th, where any team can win on their day. Look at the table as it stands:
Based on performances this season, could you really make a case where Tigers are *that* much better than Worcester or Falcons, particularly since the start of the year? We've been fortunate that Gussy's impact has led to a good uptick in getting bonus points, not just by scoring tries but also by getting the important LBP as well. If either Falcons or Warriors had been picking up a few LBPs earlier in the season, you'd see Tigers really bricking it in either 11th or 12th at the moment...
