I thought that I read a stat that we were near the top of the league in missed tackles. FWIW, I do think that tackling has been an issue, this year and last.
IMO, a thumper at safety would be nice. I like Poyer, but the guy just doesn't seem to like sticking his nose in there and laying hits.
In a larger sense, the bend-but-don't-break style will work against guys like Fitz, Duck Hodges, Brandon Allen, Haskins, etc., but is probably not going to succeed against above average QBs, like those typically faced in the post-season.
