I think the OL and Cade are probably better than you think.Seems overly optimistic. I love Kaleb Brown and Gill was a solid addition but Anderson and Buie are unproven, and not much depth.
O line is middling at best, and more likely below average if slightly improving.
QB was a dumpster fire a few months ago. I do like the addition of Sullivan even more than Cade, who just SEEMS to be a shell of what he was at UM. Marco is electric but looks to be a long putt to get him completing 60% of passes, or even in that ballpark.
Running back is deep but not elite.
It HAS to be better. But I fear we still don’t have the horses to get over the hump.
If Cade is healthy, and indications are he will be, then it will be the first time you’ve seen him healthy. The “shell” you saw was injured 100% of the time you saw him. I like the addition of Sullivan, but a healthy McNamara is a high level B1G QB. It’s not like the kid is Joe Namath with Rams.
I’m not sure about the OL, but those poor bastards have been trying to block 8 with 5 guys for three years. A competent scheme will do wonders. If they still look bad, then they just suck.
