There are many here who agree with you. They are excited about having over 20 players with almost no experience. I strongly disagree with that approach. There is a REASON for the Practice Squad. Unless a team is in full rebuilding mode, this approach is extremely risky. Sure, it's right to carry a couple of UDFA's and a half dozen draftees and last year's group.
There is nothing wrong with developing players. Some are draftees. Some come from other teams like Vrabel and Ninkovich. But for me, there is a reasonable limit.
The offense is a school in session with Brady as the professor. Four rookie receivers for the PATRIOTS (3 WR and a TE). Wake me up from the bad dream. It will likely work out fine because we have a very experienced OL and a reasonable and deep set of running backs, and a really weak division (we play 2 of the 3-5 worst teams in the NFL in the next 2 weeks)..
On defense, we have a vey few vets, last year's kids and this year's kids. We look at their measurables and college experience and hope. We NEED no injuries to the veterans; We NEED last year's top rookies to step up, and we need contributions from this year's rookies.
This could work out. On paper this team's defense is improved.
Very young teams sometimes succeed. However, there is a reason that of the top 10 youngest teams, only a couple are serious contenders.
The only players who we should be listing as upgradeable at this point are players with at least 1 year over NFL experience; I am not prepared to pass judgment on some unless I have seen them play in a regular season game.
