My son's college coach loved 2 way players. Of course, it's easier said than done.
Over son's college time, they had four 2-way players. Two were drafted/FA. Both made it all the way. One was a SS/P; the other a 1B/P. Both were consensus all-league and one was both Player and Pitcher of the year (and likely the best all round player in league history).
In fact one pitched last nite in mop up while DHing for NYY. One made it as a pitcher, the other as a hitter. Both are still in the land between AAA and MLB. Both were fantastic athletes with incredible work ethic - doing full bull pens and then doing their position stuff. And, both graduated after signing.
The others had successful college careers; both succeeded on the mound (they weren't college level hitters).
