I know that is a bold statement but consider the following. These picks are made assuming no injuries or off field issues.
Sure NFL draft picks
Stanley
Fant
Hockensen
Wirfs
Jackson
Daniels
IKM
Possible picks
ISM
Paulsen
Young
Recinos
Defense sure picks
Nixon
Epenesa
M. Nelson
A. Nelson
Jackson (assuming he returns)
Hooker
Possibles
Hankins
Stone
Lattimore
Some of these guys are solely based on potential and limited sample size but I honestly believe there could be up to 20 guys on this roster who could play in the NFL.
Sure NFL draft picks
Stanley - Not a sure pick. Possible but work to do. At least makes a fall camp.
Fant - Yes.
Hockensen - Maybe a late round pick. At least an undrafted pickup.
Wirfs - A lot of work to do to be a pick. Barring injury should at least be an undrafted pickup.
Jackson - A lot of work to do to be a pick. Barring injury should at least be an undrafted pickup.
Daniels - Yes.
IKM - Too early.
Possible picks
ISM - Not with his hands currently. Has a lot of work to be an undrafted pickup.
Paulsen - Not even an undrafted pickup right now. Maybe in the future if everything clicks.
Young - Too early.
Recinos - Kickers rarely get picked. May get signed to a team though.
Defense sure picks
Nixon - Who knows?
Epenesa - Probably
M. Nelson - Maybe
A. Nelson - Maybe
Jackson (assuming he returns) - Absolutely
Hooker - Maybe. At least an undrafted pickup.
Possibles
Hankins - Too early
Stone - Too early
Lattimore - Too early
This is a far cry from the 2008 team that had the entire starting defense make an NFL fall camp and most of them make an active roster. Plus a ton of the backups also turn into NFL players. Not to mention all of the stars on the offensive side of the ball that year in Greene, Stanzi, DJK, McNutt(barely played), Myers, Reisner, Moeaki, and Bulaga.
The 2002 and 2003 teams were pretty stacked too. As mediocre as our pass defense was in 2002, a lot of the starters and their backups ended up playing several years in the NFL. Babineaux, Cole, Clauss, Roth, Robinson, Greenway, Hodge, Pagel, Sanders, and Considine all played meaningful years in the NFL. Hodges and DJ Johnson also got a little bit of time in the NFL too. The offense also had a ton of talent obviously. Plus a lot of NFL service time from the OL and TE starters/backups. Plus we had Kaeding.
The 2018 team is not likely to equal either of those groups I mentioned without fast forwarding 10 years to really know how good the backups ended up being.
