I would generally agree with you, but....
1. As others noted, Evans had a lot of hype in Spring ball.
2. Evans looked very, very good in those 3 carries
3. Them bringing in a transfer RB just says they found a guy who is very good, and there isn't anyone fully proven. Evans isn't fully proven in games - it doesn't say anything about their confidence in him.
To me, I love this thread because this was my #1 hobby horse this year: where the hell is Evans and why isn't he on the field?!! Listen, I'm sure Williams and Potts are great guys and I thank them for working hard in practice for the U and their commitment to their program. All that said, IMO Fleck's biggest offseason mistake was not telling Potts (and Williams to a lesser extent, but I don't mind keeping him around primarily as a 3rd-down blocker, which was largely his role) to go find a lower-level program where they could be a star or else that they were going to ride the pine if they came back. And Fleck's biggest in-season mistake was playing Potts & Williams so much. Potts & Williams clearly are not Big10 caliber backs.
If Fleck had told Irving & Thomas in the off season that they were the clear #2 & #3 guys, maybe one of them would've stayed.
The reason I care so much is that, IMO, we clearly lost 2 games this year because of the lack of an option behind Mo, and Evans looked like a clear option.
1. Purdue - Potts & Williams couldn't run at all. If Evans was healthy - and I don't know if he was - then a good RB would've allowed us at least some running yards and enough to win that game
2. Iowa - yes, Mo ran for 250 or so yards. But on that drive when he fumbled, he fumbled on his 14th (FOURTEENTH!) carry of the drive and his 10th (TENTH!!!) in a row. He was rightly exhausted, and I blame that fumble not on Mo, but on Fleck for not giving him a breather on that drive because he knew Potts and/or Williams would lose yards or get zero if put them in.
Those were the games that decided the B1G West title and I'm annoyed that Evans didn't play in those games (asterisk for Purdue, because I don't know if he was healthy). Although - like I said - if he had told Irving or Thomas that they were #2 then maybe one of them would've been back and played in those games.
Now, I have a friend who is a booster who claimed he had dinner with Fleck and Fleck told him (or implied or whatever) that the reason they didn't play Evans much is they didn't want a repeat of last year where our Freshmen RBs played and then were lured away by other schools. That's hearsay to me at this point, so I don't know how much truth there is to that. But if it's true, I find that gross malpractice by Fleck. If true, he has to prioritize winning those games and know that he could sell a different story to Evans than he could've to Irving/Thomas last year (Mo & Williams graduate, no need to play Potts next year).
Finally, I sincerely hope that Fleck tells Potts to find another school or else that he'll be riding the pine next season if he comes back here with the 3 talented guys (Evans, W Mich transfer, HS recruit from Mich) coming in. Again, I'm sure Potts is a great guy, and I don't like to even say anything negative about guys who have worked so hard for our program, but IMO Potts is just not a Big10 caliber back. If Potts is back and getting more than garbage time carries next year, I'm not gonna be happy.
