IMO the 5 "best" guys probably include a couple of guys who are redshirting. The 5 "most ready to play" though are probably starting. It's a conundrum.
One of the former players recently did something about Frost wasn't necessarily going all out this year and wanting to keep shirts on guys for the future if at all possible. Also referenced jurgens taking his lumps instead of sitting him again stockpiling some experience in lieu of absolute now performance although I'm not sure we have a real tremendous center situation anyway
Folks can have their own opinions but if that's what he wants to do then sure.
