Beat me to it St Georgio. Stanley brothers should be in the dictionary under the definition injury prone.
To me an injury prone player is someone who misses at least 6 games a season consistently. That is a quarter of your season more or less. Missing your best player for 6 games can be the difference of making the 8. Dugan hits that mark, same with Foran and definitely Peats,
Look at someone like Cam Smith, Thurston, Cronk who rarely go though a season missing 6 games. If they have it would be far more seasons that they have missed less than 6 games than missed more than 6 games.
