I can't argue with any of that but it was a comment about specific players vs non-specific players.
I'm sure some of the young LBs could take over for Matakevich for sure. I don't know about Hodgins taking over for Kumerow. Could he at WR, sure. But could he also produce on ST is another question. And Jones at RB I completely agree with but the gunner definitely something he excels at.
And yes, there are plenty of candidates to RETURN kick, the problem is a good amount of them are an unknown right now.
