Huh?
Tony Eason's career W-L as a Pats starter was 28--21 (0.571) with a QBR of 81.
Here are the career Pats' W-L records and Pats' QBR's of well-known Pats QB's not named Brady:
Grogan: 75--60 (W/L 0.556, QBR 70)
Bledsoe: 63--60 (0.512, 76)
Flutie: 8--5 (0.615, 61)
Plunkett: 23--28 (0.451, 60)
So, nobody's putting Tony in Canton or even in the HOF at Patriots Place, but the worst? "by far?"
Nope.
Eason took them to their first SB, where the team, with Grogan starting, was run over by a Freight Train called Da Bears. But he won three playoff games before that game with QBR's of 132, 104 and 131.
His lifetime Playoff Record was 3--2 (including the SB loss in which he only threw six passes) with a QBR of 115.6.
In other words, he won as many playoff games as Matt Ryan.
In fact, the only Pats QB's to win more playoff games are Bledsoe with four and Tom Brady with a hundred or so (OK, 25).
Grogan was 0--4 in the Playoffs.
