Don't normally do this, but I've been encouraged that I'm not bad at it, so I'll take a stab:
Alcorn State senior wide receiver Edward Johnson was instructed to play out of position for much of Saturday’s match up versus Mississippi Valley State.
matchup (match up is a verb. Matchup is a noun. It's that way in just about every instance.)
use "versus" sparingly. I would go with "against"
Doing so was a gamble. But a risk that helped pave the way for the Braves 27-9 thumping of the Delta Devils in the 13th annual Chicago Football Classic at Soldier Field.
one sentence. Your second sentence is an incomplete sentence. Avoid starting sentences with "And" or "But" when possible.
Braves'[b/] Avoid using nicknames when having to put an apostrophe afterward. Interchange team name with team nickname. (...for Alcorn State's 27-9 thumping ...)
WHEN at Soldier Field? Saturday? Friday?
Johnson stood on his own 30 midway through the first quarter for the first time in his college career as a punt returner.
First reference, use 30-yard line. You can say "30" on future references.
move "as a punt returner" after "30" -- "Johnson stood on his own 30 as a punt returner ..."
The maiden voyage ended 70 yards later in the south end zone to put Alcorn State up 7-0.
Here's where you can use "...put the Braves up 7-0.
“It was my first time (returning punts),” Johnson said, who all week lobbied with head coach Earnest Collins Jr. during practice to use him in that role. “It was a game-time decision.”
Awkward. "...returning punts)," said Johnson, who ..."
For his 130 all-purpose yard performance, Johnson was named the game’s offensive MVP. The Braves (2-0, 1-0) special teams unit continued to give the Delta Devils (0-3, 0-2) its in the first quarter when cornerback Kirderra Hall blocked Carlos Sanchez’s punt.
New paragraph after first sentence. The two sentences are unrelated.
Alcorn State's special teams unit
If Devils is a nickname, it's "...Delta Devils THEIR..."
The loose ball was scooped up by freshman Jacque Caldwell and run back for a touchdown to increase the Alcorn State advantage to 14-0.
This sentence needs to go with the last sentence in the previous graf.
"run back" is awkward. I would use "returned"
"to increase Alcorn State's advantage..."
“We saw some laws in their punt protection and we tried to exploit it, “Collins Jr. said. “It ended up working out for us. “People say special teams are only one-third of the game, but we work really hard on it during practice, and it paid off for us."
I assume you mean "flaws" in their punt protection.
Either omit the open quote before "People" or start a new paragraph.
Although the special teams squad provided early points, the second-year head coach replaced senior starting quarterback Terrance Barnes in the second quarter after several lackluster drives for true freshman Brandon Bridge.
Reverse "after several lackluster drives" and "for true freshman Brandon Bridge"
The Canadian-born signal-caller provided an immediate spark by rushing for 67 yards and throwing for another 127, including a 1-yard strike to Johnson just before halftime that extend the lead to 21-0.
“I feel like I can make plays both ways, “ Bridge said of his ability to beat the defense with both his right arm and scrambling ability. “It feels good that the coaches have a lot of confidence in me.”
Braves’ running back Gabriel Nash chipped in with 81 rushing yards and a touchdown. Not much could be said for a Mississippi Valley State offense that came into the game a week after being outgained in total yards 489 to 44 in a 44-0 whitewashing at South Carolina State.
You don't chip in WITH -- you just chip in.
Playing without starting quarterback Carl Davis who is out for the season with a broken leg, Holmes Community College transfer Oliver Hughes went 18-for-37 for 152 yards and an interception.
...Carl Davis, who ... watch your commas.
18 for 37. Only use hyphens when it is an adjective modifier ("...an 18-for-37 performance..." "...18-of-37 passing..."
AND a touchdown, WITH an interception. Interceptions aren't positive stats.
The offense was aided by three Alcorn State turnovers, but unable to capitalize on rare opportunities to attack with a short field, going 3-of-15 on third down conversions and 0-for-3 on fourth down.
"...turnovers and was unable to capitalize..."
3 of 15 on third down ... and 0 for 3 on fourth down
Mississippi Valley State finished the game with more total punting yards (274) than total yards on offense (265).
The Delta Devils scored their lone touchdown on a Christopher Watkins 14-yard scamper in the early stages of the fourth quarter. It was the first of the season for the beleaguered group that has now scored just 15 points through three games.
Hope that helps.
