I'm probably going to be ridiculed for this but I'm going to say it anyways - sign Lofa Tatupu.
It has been reported today on ESPN that the Falcon's had worked out Lofa and it was described by a league source as being, "very well."
Many sites are giving Lofa's past accolades as reasons for a successful, "comeback." Lofa is a three time Pro-Bowler (once as a rookie), 1x All-Pro selection, NFC champion, great blood-line, etc, etc. Then you hear about the knee-surgery, contract disputes, torn pectoral, etc, etc. Instead, I'm going to ask fellow Patriots fans to look at the tape and who does the 29-year-old Lofa remind you of?
Mock me but look at the tape.
The numbers are similar, Tedy Bruschi was listed at 6'1 and 245 pounds. When Lofa was drafted, he measured in at 6'0 and 238 pounds. Even though Tedy has had a longer career, both turn similar numbers regarding interceptions, Tedy with 12 and Lofa at 10. Both have played through tough injuries, i.e. heart attack and banged up knees. But that did not stop Tedy from performing and I don't think it will stop Lofa either.
But enough with the numbers and great story -- let's look at the tape.
Both are small, stout, strong, and instinctive. They take on and shed blocks. Both drop back in coverage. Most importantly, they make tackles. But they have on attribute that rises above all others -- they are leaders ON the field and IN the locker room. This is the Patriots way.
I don't see any reason to bring in a high character guy and former Pro-Bowler that provides depth. Additionally, he is a financially viable option as he is a year removed from playing football. As any great football player does, he is ready to prove himself again.
At a modest rate, I would take a proven commodity over a potential combine bust.
