You can feel the roster improvement by looking at the cuts, that's for damn sure. It's going to be tough. Here's what I'm thinking now for the offense:
QB (3) Stafford, Garoppolo, Bennett.
RB (4) Williams, Shrader, Corum, Hunter.
TE (4) Higbee, Parkinson, Allen, Ferguson*.
OL (8) Jackson, Avila, Shelton, Dotson, Havenstein, Limmer, McClendon, Quessenberry. <Lampkin IR>
WR(5) Nacua, Adams, Atwell, Whittington, Smith.
*= Ferguson to IR potentially, which would open up a roster spot for Mumpfield. Don't like cutting Mumpfield but ST has to be prioritized.
Now there's a chance the Rams don't have Shrader as high as I do in that room, and his cut would enable Mumpfield having a roster spot. But if they cut him he is at risk to be added to another team. Also Shrader fits well in the offense with his pass catching ability if we have Jimmy at QB early on, where he will need dumpoff targets who can RAC.
Gotta imagine we go 25/25 with offense and defense. I could see Leveston making the team as the swing guard/right tackle with D.J. Humphries as the backup at left (you kinda forgot him, but that's okay; I think everyone has). That could theoretically leave a spot for Mumpfield, even if Ferguson doesn't go on IR.
But here's my thoughts on the roster crunch:
QB (3) - Stafford*, Garoppolo, Bennett
RB (4) - Williams, Corum, Hunter, Schrader
WR (6) - Nacua, Adams, Atwell, Whittington, Smith, Mumpfield
TE (3) - Higbee, Allen, Ferguson*
OL (9) - A. Jackson, Avila, Shelton, Dotson, Havenstein, Humphries, Limmer, McClendon, Leveston. (Lampkin IR)
(All depending on Stafford's health, of course. Would roll with three if he's not ready to go with another team's cut. If Ferguson needs IR, well, there's plenty of talented tight ends on other rosters to poach. I've just seen enough of Parkinson; I'd love to see a seventh-round pick swap for him, for all I care.)
As for defense, that's tricky. I'd rather keep six DL; Desjuan Johnson has played himself into a roster spot. Wallace at safety/corner/backup STAR gives us a lot of options. Here's how I'd do it defensively:
DL (6) - Turner, Fiske, Ford, Davis, Johnson, Hamilton.
EDGE LB (6) - Verse, Young, Stewart, B. Jackson, Hampton, Thomas
ILB (4) - Landman, Speights, Paul, Dolac
CB (4) - Witherspoon, Forbes, Durant, D. Williams
SAF (5) - Lake, Curl, Kinchens, McCollough, Wallace
(Yeah, see ya, Kendrick, Reeder. Well...I guess Reeder can stay on the practice squad. Kendrick, please go far, far away.)
