You say the receivers were better. The stats don't bear that out. Travis Taylor is arguably Chris Chambers. He was finally showing signs of breaking out until Boller took over and stunk up the place. Marcus Robinson's stats perked up higher last year with the Vikings than they were with the Ravens even though Marcus was the #3 receiver for the Vikings and the #2 guy with the Ravens. Heap didn't play much last year, but he was every bit as good as McMichael ever has been prior to Boller starting. Is it a coincidence that both Heap's and Taylor's stats went down from 2002 to 2003 when Boller took over?
I'll also point out that Boller has had a better running game behind him than Jay had for years 1, 2, or 4 of his four years of solid starts. He got over 2000 yards from the ground game in 2003 and over 1700 from the ground game in 2004.
You people complain about Fiedler, but he outperformed 1st round graded talent in situations where that talent hasn't even worn out its welcome yet.
