The Philadelphia Eagles used their lone fourth-round pick (No. 123 overall) to select Zech McPhearson, a cornerback out of Texas Tech. McPhearson joins a cornerback group that includes Darius Slay and Avonte Maddox as the starters, but not much depth behind them. He'll be in contention to play immediately.

Here are three things to know about McPhearson:

McPhearson has a very athletic bloodline of talent in his family. CBS Sports NFL writer Cody Benjamin wrote an excellent feature on McPhearson and his family you should check out. This is the McPhearson family tree of athletics from Cody's piece:

McPhearson started at Penn State, before enrolling as a graduate transfer at Texas Tech. He saw time in the secondary and special teams for the Nittany Lions, but became an NFL player for the Red Raiders. He started in 21 of his 22 career games with Texas Tech and was one of four players in the nation with at least four interceptions and two fumble recoveries and one of three from a Power 5 conference.

McPhearson can play inside or outside, and should compete for snaps in the Eagles defense. Kevon Seymour is currently listed as the starting slot cornerback on the Eagles depth chart, so there is a starting job up for grabs. McPhearson will certainly benefit learning from defensive coordinator Jonathan Gannon.
