Michigan State Spartans RB Room Year-over-Year Analysis
If we want to think about YoY improvements, we need to understand what we are benchmarking off. In short, it's a low bar... and it's easy to point fingers to what led to the lack of success: 1. Not the most talented RB room. 2. OL injuries. 3. Unstable QB play. 4. Play-calling. But don't worry, there's reason for optimism (check out the Offensive Line Revamp here).

Departures (2025 Production Leaving)
Even with poor national rankings in rushing, it's worth noting the departing stats to understand how they are being replaced.
M. Frazier (Portal)
116 carries, 520 yards (4.5 YPC), 2 TD
Added limited value in passing game (12 catches, 25 yards). PFF supports this with a 61.1 Receiving Grade.
What we are loosing: steady, replacement-level early-down back
PFF context: functional but not a play driver
E. Tau-Tolliver (Graduation)
72 carries, 428 yards (5.9 YPC), 2 TD
18 catches, 139 yards. This was his strength, supported by 72 PFF Receiving Grade
True efficiency back with burst and receiving ability
PFF grades suggest a space player and complementary 3rd down back.
Net loss: ~950 rushing yards, but much of it came without explosiveness or high TD impact
Additions (Why This Is a Clear Upgrade)
Cam Edwards (UConn) Senior — RB1
Career profile
3-year producer
Career YPC: 5.6
2025: 1,200+ rushing yards, 15 TD. Great 87 PFF Run Grade.
Receiving: 13+ catches, 130+ yards 3 seasons in a row. Solid 65 PFF Receivin Grade
Skill set
True three-down back
Between-the-tackles power with burst
Proven red-zone finisher
Legitimate passing-game value
Strong Pass Blocker with a 70 Pass Block Grade
➡️ Upgrade over both Frazier and Tau-Tolliver combined
More efficient
More durable
More scoring
Marvis Parrish Sophmore — RB2 / Change of Pace
2025: 576 yards, 5.4 YPC. PFF Run Grade of 78.
36 receptions. Capable PFF Receiving Grade of 61.
C-USA All-Freshman
Skill set
Speed + lateral burst
Space weapon
Mismatch vs linebackers
Screen / angle / perimeter threat
➡️ Replaces Tau-Tolliver’s explosiveness and then some, with more receiving upside.
Patterson (Iowa) Senior — RB3
Career: ~800 yards, 4 TD.
2025: 300 yards, 5.2 YPC in 9 games.
Skill set
Downhill, no-nonsense runner
Vision + pad level
Trustworthy rotational back
➡️ Raises the floor of the room — fewer wasted snaps when RB1/RB2 are off the field.
Returning Piece
Brandon Tullis
69 carries, 301 yards (4.4 YPC), 4 TD. Run grade of 72, per PFF.
11 receptions, 82 yards. Capable Receiving grade of 65, per PFF.
Context matters
Ran behind an inconsistent OL
Often used situationally
PFF grades were volatile week-to-week
Role in 2026
RB3/RB4 flexibility
Short-yardage, relief carries
Insurance with experience
➡️ Tullis slides from “needed contributor” to “luxury depth” — a healthy shift.
Production Swap: In vs Out
2025 Production Leaving
~188 carries
~948 rushing yards
~4 TD
Moderate receiving impact
Career / Recent Production Coming In
443 carries
~2,500 rushing yards
20 TD
5.75 YPC
Legit receiving resumes across the board
➡️ This is not lateral. This is a clear talent + efficiency upgrade.
Skill Set Evolution (YoY)
Trait | 2025 RB Room | 2026 RB Room |
RB1 Quality | Solid | High-end, proven |
Explosiveness | Inconsistent | Multiple sources |
Receiving Threat | Limited | Multiple backs |
TD Reliability | Spotty | Bankable |
Role Clarity | Blurry | Very defined |
Injury Cushion | Thin | Strong |
Receiving Back
It's worth noting how Edwards and Parrish can work in the passing game. Let's look at 2025 numbers to guide us:
Marvis Parrish
How he was used
77.5% of targets behind the LOS
93.5% catch rate on those looks
5.3 YAC per reception
Very limited targets beyond 5–7 yards
Minimal route responsibility; touches were manufactured
What that tells us
Parrish wasn’t asked to run the passing game
He was asked to turn space into yards
High efficiency when schemed, low margin when freelancing
Cam Edwards
How he was used
Balanced target distribution:
~41% behind LOS
~55% short (0–9 yards)
Some medium-depth usage
Strong catch efficiency across all areas
High YAC within structure, not just on screens
Trusted on real routes (angles, flats, checkdowns)
What that tells us
Edwards was a functional part of the route tree
Comfortable catching in traffic
Reliable outlet on broken plays and pressure looks
Role Translation: 2025 → 2026
Parrish in 2026
Projected role
Designed-touch specialist
Motion player
Screen / swing / flare usage
Perimeter stressor
How MSU should use him
4–8 touches per game
High leverage situations
Space creation, not volume accumulation
Edwards in 2026
Projected role
True three-down back
Primary checkdown option
3rd-down and 2-minute offense RB
How MSU should use him
Full route participation
Protection + release responsibilities
Extension of the run game on early downs
Why This Pairing Works (Big Picture)
Trait | Edwards | Parrish |
Route diversity | ✅ | ❌ |
Designed touches | Secondary | Primary |
LOS usage | Complement | Core |
Short-yard routes | Strength | Limited |
Pass protection | Functional | Liability |
Snap trust | High | Situational |
Key takeaway
Edwards handles the infrastructure of the passing game
Parrish supplies the explosiveness
No overlap, no redundancy
In 2025, Edwards proved he could function as a true receiving back within structure, while Parrish thrived as a manufactured-touch weapon; in 2026, Michigan State can lean into both roles without forcing either player outside his strengths.
Snapshot: What Changed at a High Level
Out: Volume without explosion (Frazier), efficiency + versatility (Tau-Tolliver)
In: Proven production, higher efficiency, more receiving juice, clearer role definition
Net Effect: Fewer “just guys,” more defined skill sets, higher ceiling per touch
Bottom Line
Michigan State traded volume for efficiency
Added a true RB1 instead of a committee headliner
Increased receiving versatility without sacrificing power
Turned Brandon Tullis into depth instead of necessity
Raised both ceiling and floor of the room
We expect the offensive line to take a step forward (check out why here). This RB group will benefit from the OLine improvement, and we will see it with more explosive plays and more drive-to-drive consistency. From a coaching standpoint, I'd expect them to be far more difficult to game-plan against than in 2025.
