The Eagles gave up a fifth round pick in this week's draft for weak side linebacker Ernie Sims.
Sims was one of the few bright spots for the dismal Lions over the last few seasons.
Sims had 100 tackles in each of his NFL seasons, aside from last season in which Sims missed a good portion of the year.
The Eagles lost Will Witherspoon and Chris Gocong this offseason leaving the linebacking corps with one returning starter, middle linebacker Stewart Bradley.
The Eagles front seven left something to be desired last season, and Sims adds athleticism and talent to an under-performing defense.
Sims is a former ninth overall pick out of Florida State. He ran a 4.55 40 yard at the NFL combine coming out of college.
The Eagles were able to add an athletic sure tackler for a fifth-round pick to sure up their defense.
The Eagles draft plans will likely change after this acquisition. The Eagles no longer need a weak side linebacker, and with Bradley returning, need only a strong side linebacker.
The only Eagles linebacker with ideal strong side size is aside from middle linebacker Stewart Bradley is third year man Joe Mays, who lacks experience.
Another option is Omar Gaither. Gaither beat out Joe Mays to fill in for Bradley at middle linebacker last season. Gaither lacks ideal size, at 235 pounds.
Sean Weatherspoon, Sean Lee, Navorro Bowman, and Brandon Spikes could all be options in the draft.
Lee has a history of injuries which may scare away the Eagles but he is a talented outside or inside linebacker. At only 235 pounds Lee is a little undersized to play strong side.
Bowman has the talent, but has character issues. If he gets his act together he could be an elite linebacker. Bowman has the ideal size, but plays more like a weak side linebacker.
Brandon Spikes is a talented inside linbacker with plenty of size at nearly 250 pounds that could potentially convert to the strong side, but lacks ideal speed with a 40 time above five seconds.
Weatherspoon is talented, has good athleticism, and decent size. He projects as an inside or weak side linebacker though.
If the Eagles trade up for a guy like Rolando McClain that would be a very good option, but seems unlikely. If the Eagles trade up it will likely be for a safety like Eric Berry.
