Senior Bowl practice on Wednesday was moved indoors due to torrential rain in Mobile. With limited space, members of the media were unable to attend. This will be shorter than normal because all I can work off of is the limited amount of video posted online, aired on NFL Network and what was described by the pool reporters at each practice.
• Duke's Daniel Jones threw two interceptions during practice, with Delaware's Nassir Adderley jumping a route to the flat for what would have been a pick six, and South Dakota State's Jordan Brown jumping a route of his own. Adderley could be a late first round or early second round pick. He has cornerback coverage skills that he utilizes well as a ball hawk at free safety
• Stetson's Donald Parham looks more like a small forward than a tight end at 6-8 and 221 pounds. He has potential as a receiver, but had to exit practice early due to an ankle injury.
• Wide receiver Penny Hart from Georgia State is just 5-8, but he has tremendous quickness. He gets a lot of separation at the top of the route and gave defensive backs fits for the second straight day.
• UMass's Andy Isabella continues to get separation, but he had a drop for the second straight day on relatively easy catches.
• Small school defensive lineman John Cominsky (Charleston) was active on the defensive line and showed why he has big-time potential at 6-5 and 275 pounds. He was a quarterback in high school but transitioned to defensive end at Charleston.
• The one-on-one matchup between wide receiver Deebo Samuel and Rock Ya-Sin stole all the attention at practice. Ya-Sin and Samuel both won some of the battles, but Samuel had the play of the day when he adjusted to an underthrown ball in the air to make a tough catch near the sideline in front of Ya-Sin. Ya-Sin is rated by most draft experts as the best cornerback at the combine despite checking in at 5-11, three inches shorter than the 6-2 he was listed at when he attended Temple. His long arms make up for some of his height issues.
• Montez Sweat made his presence felt a few times, getting pressure off the edge.
• Oli Udoh, an invitee from the East-West Shrine Game, has played well at right tackle. Despite checking in at a massive 6-6 and 365 pounds, he looked quick enough to hold up at right tackle.
• Left tackle Andre Dillard had some good reps and others when he struggled. He needs to get more consistent.
• Neither Jaylon Ferguson nor Oshane Ximinez, two players with prolific sack numbers from smaller schools have yet to make their mark in Mobile.
