PAHOKEE, Fla. – I had an interesting encounter during 49ers receiver Anquan Boldin's charity event at PGA National last week. It made me feel old.

A group of teenagers were waiting for the NFL players to show up on the golf course as part of the 11th-annual Q Fest, which is an event to raise funds for the Anquan Boldin Foundation. One of the kids asked who would be there, and I told him Boldin, Cardinals receiver Larry Fitzgerald and Hall of Fame running back Marcus Allen.

"Who is Marcus Allen?" was the response. I just shook my head.

Now, understandably, kids today aren't expected to know about every former NFL player, even Hall of Famers. But Allen played until 1997. It didn't seem so long ago he was even helping Fantasy owners win leagues, and he scored 11 touchdowns in his final season.

I was excited to talk to Allen about running backs changing teams since he made a successful transition from the Raiders to the Chiefs. He had some good insight on the challenges facing DeMarco Murray and LeSean McCoy this season.

In case you don't know about Allen's career, he was a star with the Raiders from 1982-1992, but he had a rocky relationship with then owner Al Davis, which forced his exit to Kansas City in 1993. Despite joining the Chiefs at 33 years old, Allen ended his career with 47 total touchdowns in his final five years.

Based on his situation and what happened in Oakland, he said a big key for Murray and McCoy is if "a team really wants you," which appears to be the case. Murray left Dallas as a free agent to sign in Philadelphia, and the Bills made a significant investment to trade for McCoy from the Eagles.

Allen said the change in offense could impact Murray, as well as Ryan Mathews, who also is with a new team after leaving San Diego as a free agent for Philadelphia.

"It's a different system," Allen said. "The system was completely different in Dallas. I certainly think he's a great runner, but it remains to be seen how he'll fit, as well as Ryan Mathews from San Diego. Going from a power running system to a read option or zone read, however you want to call it. It's different. We'll find out if it's a monumental difference or minute."

Allen said McCoy could have a similar challenge leaving Chip Kelly's system and playing in Buffalo.

"We'll really have to see," Allen said. "There's only been a few backs who have played in every single system."

He said what would ease the transition going to a new team is a great quarterback, which Murray and McCoy don't have with their respective teams. Allen does like that the Eagles have a good offensive line, which should help Murray, and McCoy should get plenty of work for Rex Ryan.

From a Fantasy perspective, I'd rather have McCoy than Murray. McCoy should dominate touches in Buffalo, and I still consider him a No. 1 Fantasy running back worth drafting in Round 1.

I wouldn't draft Murray until Round 3 because I'm concerned about his workload from last year, which was 497 total touches, including the playoffs, and his injury history. He'll also share touches with Mathews and Darren Sproles, and that should drastically lower his value from 2014.

We'll find out who does better between Murray and McCoy, and if either can do what Allen did, which is change teams and still have plenty of success.
