Since you asked...
"He's won 17-games in his two seasons in Colorado Springs."
- shouldn't be a dash there
"it very well could be its receiving corp."
- should be corps
"They return just 27% of its rushing yardage, only 19% of its receiving yardage."
- subject/verb agreement; should either be It/its or They/theirs
"Northwestern will stop people at times, so will have a chance in some games."
- missing pronoun
"I have a hunch that Kevin Cosgrove's defense will be up to the challenge in the Big Ten opener."
- factual inaccuracy; Cosgrove/Lee are co-coordinators
"The Badgers played a school-record six games"
- shouldn't be a dash there
"Presumably, this will be a close game, decided in the game's final minutes."
- awkward structure
"We like Adam Weber a whole lot more than Dusin Sherer."
-misspelled Dustin
"they play @ Oregon"
- shouldn't use @ in formal writing
"They return 13 starters (4 off., 7 def., 2 special teams). Among its losses: quarterback Curtis Painter, running back Kory Sheets, and wide receivers Desmond Tardy and Greg Orton."
- subject/verb agreement, same as before
"That is problematic if you're a loyal Boilermakers observer, not if you're a Gophers fan."
- missing conjunction; should be "but," "although," or "though" before "not"
"Final Verdict: WIN ( 5-1)"
- extra space between the open parenthesis and 5
"(It was 34-7 before two late, meaningless scores made the final 34-21)"
- "it" should not be capitalized
"14 starters return (6 off., 8 def.) for arguably the best coach in the conference"
- shouldn't start a sentence with numerals
"Jewel Hampton replaces Shonn Greene at tailback - how much remains to be seen."
- I don't understand this sentence. Do you mean "how well"?
"The Hawkeyes embarrased the Gophers"
- misspelled "embarrassed"
"there may be a sign or two eluding to that game"
- misspelled "alluding"
" I respectfully disagreed with a friend, when he threw out the idea of an extension following the win at Illinois last year."
- shouldn't be a comma there
"It's a monster year for Brewster, entering year three."
- as currently constructed, it states that the monster year is entering year three; after comma should state "as he enters year three" or something similar
And all of this is leaving out numerous stylistic changes I would make.
