49. Joe Tryon, EDGE, Washington
50. Wyatt Davis, IOL, Ohio State

Miami edge rusher Gregory Rousseau fell several spots to No. 42 overall. Ohio State offensive guard Wyatt Davis and Alabama defensive tackle Christian Barmore were two others in descent. From No. 37-41, there are four cornerbacks: South Carolina's Jaycee Horn, Northwestern's Greg Newsome II, UCF's Aaron Robinson and Kentucky's Kelvin Joseph. Teams will be sorting through that group of players. Clemson's Travis Etienne is the first running back to make the list.

51. D'Wayne Eskridge, WR, Western Michigan
52. Javonte Williams, RB, North Carolina
53. Jevon Holland, S, Oregon

71. Ar'Darius Washington, S, TCU
72. Payton Turner, DL, Houston
73. Brevin Jordan, TE, Miami
74. Eric Stokes, CB, Georgia
75. Kyle Trask, QB, Florida

Oklahoma center Creed Humphrey stands out as a great value in this range. Alabama center Landon Dickerson has battled injuries but has the ability to be taken in the first round. Tennessee offensive guard Trey Smith is one of the biggest fallers, along with Humphrey, in this grouping. Florida quarterback Kyle Trask is the sixth rated quarterback, after the five projected to go in the first round.

76. Deonte Brown, IOL, Alabama
77. Baron Browning, LB, Ohio State
78. Michael Carter, RB, North Carolina
79. Amon-Ra St. Brown, WR, USC

97. Tommy Tremble, TE, Notre Dame
98. Liam Eichenberg, OT, Notre Dame
99. Thomas Graham Jr., CB, Oregon
100. Paulson Adebo, CB, Stanford

Alabama linebacker Dylan Moses is in one of the steepest declines, similar to the one Mack Wilson went through a few years ago. Clemson wide receiver Amari Rodgers stands out as one of the safest players in the draft. Ohio State center Josh Myers is another who fell substantially. Stanford offensive tackle Walker Little has essentially been off the grid because of injuries and an opt out this past season. 

101. Chris Rumph II, EDGE, Duke
102. Jordan Smith, EDGE, UAB
103. Jaylen Twyman, IDL, Pittsburgh
104. Darius Stills, IDL, West Virginia
105. Dyami Brown, WR, North Carolina
106. Victor Dimukeje, EDGE, Duke
107. Marlon Williams, WR, UCF
108. Hamilcar Rashed Jr., EDGE, Oregon State
109. Seth Williams, WR, Auburn
110. Jamien Sherwood, S, Auburn
111. Jamie Newman, QB, Georgia
112. Trey Sermon, RB, Ohio State
113. Dazz Newsome, WR, North Carolina
114. Marvin Wilson, IDL, Florida State
115. Shakur Brown, CB, Michigan State
116. Spencer Brown, OT, Northern Iowa
117. Damonte Coxie, WR, Memphis
118. Cornell Powell, WR, Clemson
119. Robert Jones, IOL, Middle Tennessee State
120. Shaun Wade, CB, Ohio State
121. Josh Palmer, WR, Tennessee
122. Tamorrion Terry, WR, Florida State
123. Pete Werner, LB, Ohio State
124. Camryn Bynum, CB, California
125. Kellen Mond, QB, Texas A&M

UAB edge rusher Jordan Smith has immense potential. His natural ability to bend around the corner is among the best in the class. Oregon State's Hamilcar Rashed Jr. has been misused in college and could be a steal if he lands in Tennessee, Indianapolis or another destination that will utilize him as a stand-up edge rusher. Ohio State cornerback Shaun Wade is one of the free falling talents. Northern Iowa offensive tackle Spencer Brown is mobile and athletic. Brown has been working out with former NFL offensive tackle Joe Staley. 

126. Aaron Banks, IOL, Notre Dame
127. Ihmir Smith-Marsette, WR, Iowa
128. Drake Jackson, IOL, Kentucky
129. Joshua Kaindoh, EDGE, Florida State
130. Tedarrell Slaton, IDL, Florida
131. Shaka Toney, EDGE, Penn State
132. Tyree Gillespie, S, Missouri
133. Larry Borom, OT, Missouri
134. Chatarius Atwell, WR, Louisville
135. Jaret Patterson, RB, Buffalo
136. Tommy Togiai, DT, Ohio State
137. Kylin Hill, RB, Mississippi State
138. Cameron McGrone, LB, Michigan
139. Justin Hilliard, LB, Ohio State
140. Ambry Thomas, CB, Michigan
141. Khalil Herbert, RB, Virginia Tech
142. Rodarius Williams, CB, Oklahoma State
143. Demetric Felton, RB, UCLA
144. Paris Ford, S, Pittsburgh
145. Marco Wilson, CB, Florida
146. Kary Vincent Jr., CB, LSU
147. Reed Blankenship, S, Middle Tennessee
148. Brady Christensen, OT, BYU
149. Chuba Hubbard, RB, Oklahoma State
150. Jaelon Darden, WR, North Texas

Oklahoma State running back Chuba Hubbard was one of college football's most dynamic talents. In general, this grouping has a lot of versatility and speed. Louisville wide receiver Chatarius "Tutu" Atwell, Buffalo running back Jaret Patterson, Virginia Tech running back Khalil Herbert, UCLA running back Demetric Felton and North Texas wide receiver Jaelon Darden are capable of reaching the end zone on any given touch.
