Free-agent tackle Jake Long, who visited the New York Giants two months ago, was visiting again Wednesday, sources said. A second visit indicates the Giants have some level of interest in adding the former No. 1 pick to their mix at tackle, where they have major question marks in the wake of the offseason injury to starting left tackle Will Beatty.

When Long visited the Giants in late May, the visit was described as a check-in on Long's rehab from ACL surgery he had nine months ago and a chance for him to see their facility and talk with their coaches. At the time, the Giants' plan was to continue to monitor his recovery and evaluate whether he made sense for them.

Long visited with the Atlanta Falcons on Tuesday, and the fact that he's taking visits with multiple teams and seeing the Giants again indicates that he, at least, believes he's ready to sign with someone and get to camp. It is possible, if the team's doctors like what they see, that he could agree to terms with the Giants on Wednesday and report to camp with them Thursday.

However, I'd caution against assuming Long is a solution as a starter, in spite of the Giants' obvious questions there. He's recovering from a second major knee surgery in as many years and is no sure thing to be able to play, let alone start at left tackle. If the Giants do sign him, it would be because they're willing to take a low-risk chance that he can help them as a backup or a mentor or maybe, once fully healthy, an option to start at left or right tackle. But it would always be a what-if, the way veteran wide receiver Mario Manningham was when they brought him and his bum knee to camp last year.

Beatty tore his pectoral muscle lifting weights in May. After that, during spring practices, the Giants moved rookie Ereck Flowers to left tackle and Marshall Newhouse to right tackle. Flowers was the No. 9 pick in this year's draft, and the Giants view him as an eventual NFL left tackle, but at the time they drafted him they were not planning to play him there right away. Newhouse was signed as a backup. So if Long does show them he's healthy and can play the way he used to play, there's certainly an opportunity for him to earn playing time. But right now, it's all a big "if."
