Tight End Jacob Maxwell
Jacob Maxwell is a 6'4", 249-pound tight end from Louisiana-Lafayette. He has solid athleticism with as evidenced by his 4.68 40. According to RajunCajuns.com, he totaled just 12 catches for 158 yards and a pair of scores. It's hard to think he'll make the team with all the tight ends already on the roster.
Safety Gabe Lynn
The Oklahoma safety has good size at 6'2" and 206 pounds. He doesn't have the natural skills to stick in the league, though, with a 33" vertical leap. He finished last season with 57 tackles and four picks, per cfbstats.com.
Quarterback James Franklin
James Franklin is an interesting prospect who offers something different than the quarterbacks on the roster: running ability. He posted 981 rushing yards and 36 total touchdowns in 2011, per Sports-Reference.com. His production was scaled down over the next two years, but that was probably a coaching decision.
Safety Jerome Couplin
Small-school safety Jerome Couplin packs a big punch. He's a hard hitter who matches the intensity of his tackling with a decent 4.55 40 and a ridiculous 41.5" vertical. There's a decent possibility that his athleticism warrants a long-term investment (i.e. the practice squad).
Wide Receiver Andrew Peacock
Besides a great name, Andrew Peacock probably won't have a lot to offer the Lions. He lacks top-end speed (4.72 speed) and is just 5'9". He does, however, have solid hands. He posted 79 receptions in 2013 alone.
Offensive Line Cornelius Lucas
The most likely candidate to make the team is the massive tackle from Kansas State. Cornelius Lucas stands 6'8" and checks in at 325 pounds. However, the most telling detail came in the form of a $20,000 signing bonus, per Aaron Wilson of The Baltimore Sun. Teams don't hand out signing bonuses unless there is a lot of competition for the player, meaning he's one of the better free agents out there.
Safety Garrett Waggoner
Fans can rightfully get excited about Garrett Waggoner's athleticism. The Dartmouth safety didn't get a lot of predraft burn because, well, he played for Dartmouth. But the 6'0", 224-pound prospect with the 39.5" vertical will have to make the roster before he goes about trying to make the team, per Aaron Wilson.
Offensive Tackle Jake Olson
The tackle from Central Michigan stands 6'4" and 301 pounds. He isn't as big as the other tackle signees, but he's big enough to handle the job. He started over Eric Fisher two years in a row but might not have the durability to last.
Offensive Tackle A.J. Dalton
A.J. Dalton is just a hair heavier than Jake Olson, standing 6'4" and weighing 307 pounds. He put up decent numbers at his pro day with a 5.25 40-yard dash, 29 bench reps, 26" vertical jump and a 7.69 three-cone drill.
Cornerback Mohammed Seisay
Mohammed Seisay is exactly the type of cornerback defensive coordinator Teryl Austin wants checking in at 6'2" with a 39" vertical. While he has the raw numbers, it's a bit curious that he wasn't able to crack the starting lineup at Nebraska.
Defensive Tackle Greg Hickman
Greg Hickman was a curious pickup for the Lions. The defensive tackle from Florida International only weighs 278 pounds and his 4.89 40-yard dash suggests that he doesn't have the speed to handle a shift to defensive end.
Fullback Chad Abram
Chad Abram was brought in to push Jed Collins for his spot as the lone fullback on the roster. It's impossible to carry two, and that's a shame because Abram has the athleticism and size to handle the job. It will be a shame if he gets cut, but hopefully he can put together enough tape to land a shot elsewhere.
