At this point in the offseason, the only players without a team are established veterans who will wait until training camp is underway, and younger guys who just can't find a suitor. For those younger players, the lack of interest forces them to other professional leagues or even into early retirement.
Unfortunately, former Browns third-round pick Siaki Ika fits in the latter. After being released by Kansas City in June, Ika hasn't found another team to join for training camp yet. The fact that he has been on three teams in two years as a third-round pick and is without a home this close to training camp is not a good sign for his chances going forward.
