Until Ellis Hobbs stepped in our CBs were almost never close enough to get a PI call, so all I take from Law's penalties is "at least he was closer to the WR than 8 yards behind!"
I'm being partially tongue in cheek, but anyone that thinks that the play of our secondary last season couldn't stand some improvement simply wasn't watching. Ty Law is on his way down, but he's still higher than any CB we've got.
Ellis Hobbs has great potential, but he's not there yet and he's only one guy. Asante turned into Duane Starks for much of the season after Starks was benched/injured/whatever (he had a few Sportscenter big hits, sure, but in general last season his coverage was awful). Gay and Scott are question marks because of their injuries and lack of experience in our system and Hank Poteat has nothing but his Bongos. Who knows what Eric Warfield brings to the table.
If we sign Law it's a huge upgrade for us. He's got tons of experience in our system and his skills, while declining, are still higher than any other CB on our roster at the present time.
