Kyle Williams shows promise but is dogged by injuries.
The San Francisco 49ers' weakest position group is their wide receiver corps. Michael Crabtree's injury is a major blow to the 49ers, and the team is looking for others to step up to the challenge.
Kyle Williams is entering his fourth season with the 49ers and has shown flashes of being a very good player. Williams has the inside track to claiming a starting job at wide receiver, opposite Anquan Boldin.
However, Williams' health issues always seem to get in the way of his progress. Even dating back to his collegiate days at Arizona State, Williams has never stayed healthy for an entire season.
When Williams joined the 49ers in 2010, they envisioned a quick slot receiver who would also contribute on special teams. In 2012, Williams missed the final five games of the regular season and postseason with a knee injury.
When healthy, Williams has the ability to make big plays. Unfortunately, he is already off to a slow start in training camp.
Williams has been slowed by a strained hamstring, and it's the type of injury he must be careful of. At this stage of his career, with a long history of injuries, Williams is proving to be a player the 49ers cannot rely on to stay healthy.
With Crabtree out, Williams needs to seize this opportunity. Once again, however, it does not look like Williams can avoid the injury bug.
At this point, if other receivers prove they can play, Williams' job could be in jeopardy. He is too brittle to be counted on and the 49ers will ultimately tire of his inability to stay on the field.
