Which stats are those, exactly? Just looking at modern QBs, his stats don't compare very favorably to players like Brady, Brees, Rodgers, or his brother. His stats are actually pretty comparable to someone like Donovan McNabb, with Eli coming out just ahead. Philip Rivers has better stats than Eli. Tony Romo played quite a bit less, but most of his stats are better than Eli. Big Ben has better stats than Eli. Hell, Matthew Stafford beats him in things like completion %, yards per game, and rating.
Total Yards, TDS, Completions
Eli is top eight
Behind Brady, Brees, Favre and his brother
Same as Ben and Rivers
More than Stafford, Rodgers, Romo and most old school QBs
Total yards is not as important as yards per game or yards per attempt. Even that is not that important if you are trying to compare modern QBs to those who played in earlier eras, as the passing game has changed a great deal over time.
Total TDs is not as important as TD % or TDs per game.
Completions is not as important as completion %.
Total numbers are stats which can look great if a player is around for a long time, but don't necessarily indicate anything about how the player performed. For example, while Stafford has fewer completions than Manning, he has a better completion %. Stafford has fewer yards, but more yards per game and just a bit higher yards per attempt. Manning has a just slightly better TD %, but a worse INT %. In many categories Stafford is better on a per-pass basis or per-game basis, and Matthew Stafford isn't even sniffing top 10 quarterbacks.
If longevity is how you judge a QB, Eli Manning is one of the greats. The only reason he has some stats better than players like Aaron Rodgers is that he's played longer, allowing him to amass higher totals. Rodgers has more yards per game, higher completion %, much higher TD %, much lower INT %, much higher rating. Even comparing the two as if they might be close to equals as QBs go is, frankly, ludicrous.
Manning is tied with Flacco for #42 all time in passer rating. He's #14 in interceptions. #15 in yards per game (pretty good actually). Tied for #85 in yards per attempt and #52 in adjusted yards per attempt. Tied for #40 in completion %. Tied for #48 in INT %. Tied for #68 in TD % (tied with Dan Fouts, actually).

Eli has not been a horrible QB by any means, but neither has he been elite, certainly he's not been a top 10 QB all time. I'd argue that he's had times in his career he wasn't even a top 10 QB playing that year.
