Sometimes highly rated QB recruits just never pan out no matter how great the coach. You will find out with Marve real quick. He hasn't looked all that good with Purdue which is a more passer friendly offense.
Looking back at the game Saturday, I found more fault in Miami's WRs than Harris's throwing ability. 2 of those INTs were direct results of WRs messing up versus bad throws. And then he threw some great balls that were simply dropped and if they were caught it would have been a different game.
Also it wasn't if Harris was going against a bad defense. Ohio State will make ALOT of QBs look bad. Have done it for years.
Harris should improve as the season goes along. What he does the rest of the season will really answer your question.
