I have no problem with him covering it.
The tweets should be sent from @newsstarsports at very least though. How many ULM fans realistically follow @TDARaginCajuns compared to The News Star's sports account? The main subset of people seeing those tweets about the ULM game were Cajun fans who have likely have a minimal passing interest and certainly arent really going to be looking for play by play tweets on it. Its a pretty easy matter of letting him have the login for that TNS account during the game. As best I can tell, only one tweet was sent during the game from that TNS account during the game (link to their story with updates as game went along.)
It's just not a very logical way to use Twitter in my opinion
