No way. I think Missouri can win eight or nine games this year but wouldn't be at all surprised by seven, maybe even six.
The new staff has generated a lot of excitement off the field, but let's not forget a 5-5 team that was blown out in all five losses has to replace its five best players. Mizzou will probably be a decided favorite (10 points or more) in five games: Central Michigan, SEMO, North Texas, Vandy, South Carolina ... an underdog in three games: Texas A&M, Georgia, Florida ... with the rest as toss-up games: Kentucky, Boston College, Tennessee, Arkansas. Win the first five, lose the middle three, split the final four and you're looking at 7-5. I don't think that's unrealistic at all - or by any means a failure.
It's fair to say the program's current roster/recruiting structure is built for 2022 to be the season that Mizzou can truly push Georgia/Florida in the SEC East.
Progress in 2021 would be seven or more wins ... unless there are more outcomes like last year's Georgia game or physical mismatches like the Tennessee game.
