The offensive side has success, and priorities dominated direction recently. With the offensive line and it's depth, and a good franchise quarterback, with a top shelf receiver, and a solid running group...they can be more selective now, as to depth at WR and QB. One more needs to be added at RB.
On the defensive side, the scouting department is zeroing in on candidates that fit the Marinelli defensive scheme and positional demands. This will be the start of year three in his system, and it generally takes to year four to start holding a changed system to shoulder all evaluations as to effectiveness.
Managing the future in the secondary, is a problem at present, but that has opportunity to reflect and improve as well.
The bulk of talent presently at defensive line, is young. But there is talent there. Add something like a Wilkerson via a trade down with the Jets, or a sudden pick at defensive line at #4, and that group could quickly reflect a stronger future.
I really don't see despair right now.
I would throw in a talented strong side linebacker, to defensive end, defensive tackle, strong safety, and cornerback...and all real basics have been improved significantly. That is five positions that could be added in the first four rounds, and upgraded as to the defense, significantly.
This would leave a RB, QB, and WR still needing influx...and that is where the late round picks could surface. But there are currently no 5th and 7th round picks. So, how can Dallas really improve in what is being thrown up as a valid deficiency?
