First-round draft picks get all the love, but Day 2 often make up the backbone of the team.Just looking at the Cowboys' current roster, you'll find several significant contributors- Cooper Beebe, DeMarvion Overshown, Sam Williams, Shavon Revel, and Donovan Ezeiruaku- who the team picked up in Rounds 2 or 3 of their respective drafts.There are loads of prospects in this year's class still waiting (for any number of reasons) to hear their name called who will go on to be every bit as successful as the ones who got the full hug-the-commish-and-pose-with-the-jersey moment on Thursday.The problem for the Cowboys, of course, is that the "best available" players at the start of the second round will almost certainly be long gone by the time Dallas gets back on the clock at No. 92. The team wasn't shy about turning those fifth-round picks and a seventh into two fourth-rounders on Thursday night, but there's less in the bank now, should the Cowboys have their eye on trading up for a particular second-round talent.But as unpredictable as Round 1 turned out to be, never say never.Here's a look at the best Day 2 players still available, according to USA Today's Michael Middlehurst-Schwartz.CornerbackJermod McCoy, TennesseeColton Hood, TennesseeAvieon Terrell, ClemsonChris Johnson, San Diego StateD'Angelo Ponds, IndianaTreydan Stukes, ArizonaKeionte Scott, MiamiBrandon Cisse, South CarolinaKeith Abney II, Arizona StateMalik Muhammad, TexasLinebackerJacob Rodriguez, Texas TechCashius Howell, Texas A&MCJ Allen, GeorgiaAnthony Hill Jr., TexasR Mason Thomas, OklahomaJake Golday, CincinnatiKyle Louis, PittJosiah Trotter, MissouriKeyshaun Elliott, Arizona StateKaleb Elarms-Orr, TCUWide receiverDenzel Boston, WashingtonGermie Bernard, AlabamaChris Bell, LousivilleBryce Lance, North Dakota StateChris Brazzell II, TennesseeAntonio Williams, ClemsonTed Hurst, Georgia StateZachariah Branch, GeorgiaDe'Zhaun Stribling, MississippiElijah Sarratt, IndianaOffensive lineOG Emmanuel Pregnon, OregonOG Chase Bisontis, Texas A&MOT Gennings Dunker, IowaOC Connor Lew, AuburnOC Sam Hecht, Kansas StateOC Jake Slaughter, FloridaOT Dametrious Crownover, Texas A&MTight endEli Stowers, VanderbiltMax Clare, Ohio StateOscar Delp, GeorgiaJustin Joly, North Carolina StateSam Roush, StanfordRunning backMike Washington Jr., ArkansasEmmett Johnson, NebraskaJonah Coleman, WashingtonDemond Claiborne, Wake ForestKaytron Allen, Penn StateEli Heidenreich, NavySafetyEmmanuel McNeil-Warren, ToledoBud Clark, TCUVJ Payne, Kansas StateDefensive endZion Young, MissouriT.J.
