Tebowmania may be dead and gone -- but Blake Shelton is still PISSED about it ... claiming Tim Tebow BELONGS in the NFL 'cause he's better than a bunch of the crappy QBs that are playing right now.
By the way, Blake is dead serious about it ... and explained in a series of pro-Tebow tweets:
"Just saw the 2011 playoff game with Steelers vs Broncos.. Can someone please give me a good reason Tim Tebo isn't playing in the NFL?!"
"I mean are you telling me that there's NOT a team that needs him out there?
