Tim NewcombFor what it's worth, I now have almost 300 M101-4/5, and not a single one that's unequivocally a Sporting News number. In other words, I have some where the player has the same number in both sets, but none where he's clearly an M101-5.
So if even Lew or someone else confirms that M101-5 can be found with TSN backs, I'd argue that they were extremely scarce.
Cheers,
