Might also have something to do with Montgomery having poor hands, and that's why he's playing RB...

He does offer something in the return game, though...

ProFootball Reference: Ty Montgomery Career Stats

Poor hands? PFR says he has a 73.6% career catch rate. That's not bad. By comparison Todd Gurley's career catch rate is 72.4% and I've never heard anyone say he has poor hands.

Montgomery really only had one bad receiving year and that was when he played for Baltimore. His catch % was 62.5 that season. The team rate was only 60%.

In his first season before he played RB he had a 78.9% rate. That's very good. I think it would be hard to say he has "poor hands."

I was under the impression he switched to RB because Eddie Lacey and James Starks got injured and they were desperate. Randall Cobb was even lining up in the backfield at times.

Utah, he was moved from WR to RB (see scouting report) because of his hands; sure you'd agree it's different catching lobs out of the backfield vs darts downfield in coverage...

According to ProFootball Reference, since joining the league, he's not even in the top 200 on catch rate for RBs...

That was the point I was making about his position designation; and one of the pluses of his addition to the roster is that he'd been a solid return guy except for one gaffe Packers fans couldn't forget...
