Lions take a look at UConn TE Sean McQuillan

Of the seven players eligible for this year's Supplemental Draft, the Detroit Lions have scouted at least four of them in person. Last week, the Lions attended West Georgia's pro day, giving them a chance to see defensive end Darrius Caldwell and defensive tackle Dalvon Stuckey. Then, on Wednesday, they visited the pro day of North Carolina Central wide receiver/kick returner Adrian Wilkins, and it turns out they also attended UConn tight end Sean McQuillan's workout.

In addition to these four players, there's a good chance the Lions were at the pro day for Clemson offensive tackle Isaiah Battle, who could be selected in the Supplemental Draft on Thursday. I say that because 26 teams were reportedly at his pro day, and given the Lions' interest in some of these lower-profile players, I would imagine they took an up-close look at Battle as well.

As for McQuillan, I can't imagine the Lions have any interest in submitting a pick for him. If he goes undrafted, however, the Lions could certainly bring him in as a free agent. They have an open spot on their roster right now, and they could use a boost in the depth department at tight end with Joseph Fauria's health still a bit up in the air. I can't imagine McQuillan would be a real threat to make the 53-man roster, but like with some of these other players in the Supplemental Draft, it wouldn't hurt to give him a look during training camp.
