49ers roster: 3 most overhyped rookies entering training camp
By Peter Panacy

No. 2: 49ers Running Back JaMycal Hasty
For the record, huge fan of former Baylor running back JaMycal Hasty here. All one needs to do is look at his short-but-stout 5-foot-8, 203-pound frame to understand how he’s such an elusive tackle. For defensive players, it’s like trying to tackle a fast-moving tree stump.
And Hasty’s one-cut abilities are pretty exciting to watch, too:
One could make the argument San Francisco’s undrafted free agent stands a great chance making the 53-man roster this season. Even though it’s a crowded group entering training camp, Hasty’s production as both a runner and receiver make him a seamless fit in Kyle Shanahan’s offense.
Particularly as a third-down back where pass-catching is a good skill to have.
The problem, however, is Hasty’s efforts as a pass blocker aren’t particularly great. In contrast, veteran tailback Jerick McKinnon’s pass-blocking abilities are in tune with his already-proven pass-catching skills. Barring another injury to McKinnon, Hasty looks to be only a little more than a reserve option and developmental player, as Niners Nation’s Kyle Posey pointed out.
Pass protection, especially for running backs, is vital on passing third downs. Hasty doesn’t quite have this skill, and the Niners halfback room is too crowded for him to make the 53-man squad based off his quick-cut abilities alone.
