TJ Houshmandzadeh is going to become a free agent and I think that he would be a good fit. Houshmandzadeh is 6'1''/200 lbs and has great hands. Houshmandzadeh can also be involved as a return specialist for the Eagles. Housh is a possession receiver and could end up with over 100 receptions next season. I think that Housh has been a better than Chad Ocho Cinco (Johnson) since the '05 season.
Even though Owen Daniels is a TE, he could be a great addition this offseason. The need for a tight end is the next top priority, since the overated LJ Smith is now a free agent. Last season, Daniels made the Pro Bowl as a replacement for Antonio Gates. If they sign Daniels, the offer could be matched by the Texans.
Lets say they sign Daniels. They still have to get a wide receiver, but it could be a #2 receiver. I think they could sign Marvin Harrison, who was granted his release today by the Colts. Even though his production is going down, he could still gain 800 yards a season with a team in need of a wide receiver. McNabb used to throw to Harrison at Syracuse, so he could be a major factor on McNabb's decision to re-sign with the Eagles.
TJ Houshmandzadeh is the most likely though for the Eagles, but there are many other options for the Eagles to make. Housh with McNabb and Westbrook could make a dangerous offense, ccontending for the Super Bowl.
