The Giants have signed linebacker Danny Clark to a 2-year, $4 million dollar contract.  He played in 13 games with the Texans last season and he made 51 tackles, defensed a pass, forced a fumble an intercepted 1 pass.  Clark has now played in 122 games in his NFL career and he has made 508 tackles, defensed 15 passes, has 5 sacks, forced 6 fumbles and intercepted 2 passes.  With all of the defections in the linebacking corps it appears that Clark will get a good chance to secure a starting job in 2008.
