Just because they got lucky once with a 5th round pick on LB doesnt mean they can do it every year and as you say their pick of Joseph proved that...
I think if they want him to replace him via the draft they will be going earlier than the 5th r.. probably they will have to use a top 60 pick to be sure of it...
I know we are all just speculating but from what we hear he may not be as motivated by money as the likes of Lawson and Phillips so I would try to get him signed before he hits the market,,, doesnt mean I expect him to play for chump change but if he took what I proposed earlier I think thats pretty good for both sides..
