You should have to spell out Kicker and Punter when your name is KP.
I take it you're talking about the L49s you've got. The answer would be in their builds if you can see them. I'd say as long as they got the big 4 built up before going MIA, then you'd do OK keeping them.
Since they're both boomers in this case, do you know where Vision and Confidence are at? That could be causing inconsistency issues that CPU dots could solve, at the cost of max kick/punt distances.
