Possibly Bloom is a younger version of Di Giuseppe, basically a quick skating ,north -south type of player, that Tocchet loves.
Also, if he picks up his scoring and adds a pestering component to his game al a Matt Cooke- but without the shenanigans, he could be useful. (Cooke made Keenan's starting roster after being in the OHL top 10 scoring the season before.)
All that is possible for Bloom.
