I could be wrong, but it seems dubious that Jacksonville had 19 dropped TDs last year. As for today, I believe that 3 of the 4 dropped TDs were on the same drive (which resulted in a TD).
Cap hits aside, I'd much rather take BTJ, Kirk, Davis and Engram over the Bills' ragtag receiving corps. Davis could fill the 'blocking WR' role that Beane seems to feel is essential. And no, I did not want Beane to re-sign Davis.
