Bowman obviously wasn't happy about having his snaps reduced, made it known & asked to explore trade options, and then apparently said he would accept a reduced role...this according to Lynch and Shanahan. But Lynch said he essentially felt that Bowman would never truly be happy accepting less playing time with the 49'ers...and he drew from his own experience as a player in a similar situation.
Bowman's snaps were seemingly being reduced because he was proving to be a liability in space in the 4-3. He had more ground to cover in the new scheme, and the injuries limited his ability to do so. Lynch & Shanahan also mentioned they like some of their young guys...to include Armstrong & Foster (whom they intend to have take over at Mike). They even mentioned Mark Nzeocha. Bowman may fit best in a 3-4 moving forward? With Dallas, he could definitely help with run defense which they desperately need. He's certainly better than what Dallas has been getting to this point...just not sure they'll actually pursue him.
The guy I wanted the Cowboys to pursue during regular free agency...and again more recently, was Gerald Hodges. He's 26 y/o...can play inside or outside...and originally signed a 1-year deal with the Bills for less than $800,000 (minus $80,000 signing bonus)...and very recently signed for the rest of the season with the Saints for $547,000. The signing would've thus even fit the 'cheaper' (too cheap), free agent model the team has adopted. But instead of a guy like Hodges, they go out & sign Justin March-Lillard.
While the former had some up's & downs...the following stat lines comprise 19 of Hodges 26 career starts:
2016 (12 games started w/ 49'ers): 83 tackles, 3 sacks, 2 Int's, 1 forced fumble ... FWIW (debatable), in 584 snaps last season, Hodges finished with the eighth highest overall grade of any inside LB according to PFF.
2014 (7 games started w/ Vikings): 66 tackles, 0.5 sacks, 1 Int, 7 passes defensed, 1 TD
The scenario below, could've applied to Hodges...and still could apply IF they signed Bowman. What could've been/still could be going forward for the remainder of this season:
Sam: Hitchens (when in base) ... Wilber, Wilson
Mike: Bowman (what could've been = Hodges) ... Hitchens, Smith (only in a pinch)
Will: Lee ... Smith, Hitchens (Think this may be Jaylon's best fit at this level...pace his play; let him learn behind Lee while getting a few snaps to include possibly also blitzing from the strong side on occasion. Lee is already 31 & we all know the injury history, so grooming Jaylon there makes some sense, and it may prove to be the best fit longer-term. It allows him to attempt to fully heal if able to, without being overly utilized too quickly, as he obviously isn't ready/healthy enough for a full-time role at this point).
