According to , the Lions have a whopping $34.5 million in cap space, the fourth-most in the NFL. That gives Holmes the ability to make multiple moves if he wants to further bolster Detroit's already impre sive roster.Knowing that, there are two players in particular the Lions should have their eyes on ahead of training camp. Here's a look at who they are and why Detroit needs to sign them.Signings Lions should makeWR Michael ThomasThomas is not the receiver he once was Michael Lorenzen Jersey and hasn't been able to stay healthy the Nick Senzel Jersey last four years, but it wouldn't hurt to bring him in to add more depth at wide receiver, where Kalif Raymond is currently slated to be a starter on the boundary opposite Jameson Williams.On top of his experience out wide, Thomas has also worked out of the slot, giving the Lions some options. He'll definitely come cheap and on a one-year deal, so Alex Wood Jersey there's really nothing to lose by bringing him in.DE Emmanuel OgbahThe Lions added Marcus Davenport this offseason, but that was that for significant additions along the edge, where Detroit is hoping for Davenport to thrive and take pre sure off Aidan Hutchinson. While Davenport has the ability to do that, he has dealt with injury i sues over his career, making him a question mark.Detroit Derek Dietrich Jersey can shore up the edge by bringing in Emmanuel Ogbah, who tallied 5.5 sacks in a part-time role last season.
