15 has been enough in the past (often 6 DL's and 9 LB's). I think that even with more 4-3, we could still keep the same number. DL (7) Seymour, Wilfork, Warren, Wright, Brace, Green, Pryor/Smith OLB/DE (2) Burgess, Banta-Cain OLB (3) Thomas, Woods, Crable ILB (3) Mayo, Guyton, Bruschi A 16th is certainly possible, perhaps reasonable. Lenon and Ninkovitch come to mind. 9 DB's seems to be sufficient with McGowan competing with Tank and special teamers for the 9th DB roster spot.
