ST needs more experience, we need a killer SS, and upgrades at DE would help, but overall i wouldn't say there are any problems besides wearing out and getting run over (we need more depth and rotation i guess... at least until our O doesn't totally suck)...
williams uses the blitz to try and kill the QB before anyone gets deep and the QB has time to hit them... the trade off (vs general cover 2 or deeper coverage packages) is that you sack the deep guys for pressure... both can work, but without extra blitzers, our D line doesn't have a great amount of pressure by itself (the ravens are the same way, believe it or not
), so bend don't break strategies wouldn't play as well with our roster... all imho of course, and i reserve the right to be totally wrong and completely off-base.
