Wallace had a successful journey in Pittsburgh. He was selected in the third round of the 2009 Draft and impressed people with 756 yards and 6 TDs in his rookie season. He followed up on that the next season with 1,257 yards and 10 TDs. His third season was just a tad worse than the previous, but he still did well with over 1,000 yards and 8 TDs. However, last season was terrible. Wallace was expected to do well as he was entering his fourth year, but as the season progressed, Wallace did poorly. He finished with 836 yards and 8 TDs, while his team failed to make the playoffs.
Entering the offseason, the Steelers realized Wallace may not stay as his contract had expired. As predicted, Wallace wanted more money than Pittsburgh was willing to pay. Wallace then hit the market, and teams from all over the place desired him. Only a few teams were willing to pay Wallace the money he wanted. Turns out, The highest bid for Wallace was Minnesota. However, Wallace noticed that Miami offered a very similar contract, and he chose to take the barely-cheaper contract due to the climate in Miami.
After Wallace signed with the Dolphins, he started house-searching, something he had not done in Pittsburgh. His contract (5-year, $60M) shows that he has enough to buy a pretty nice house. This just proves that Wallace is expecting to stay in Miami for a while.
Wallace has seemed excited about the team recently. He said to the press: "Everybody has a college mentality around here. It's a lot different than where I came from. Everybody's hungry. Everybody wants to get better, get to where we need to be - that's a winning record."
Wallace will be the veteran/star of the offense going into this season, especially out of the WR's. Last year, Tannehill relied on Brian Hartline to do a lot. Hartline did fine, but he struggled to be an elite red-zone target. Wallace brings upside to the receiving group as he is a solid red-zone target, and as he has averaged 17.2 yards per catch throughout his career. Mike Wallace brings all upside to this offense. Tannehill not only has a year under his belt, but he has a new elite WR. Expect Miami's offense to be solid this season, and expect Wallace to show that he is worth the $60M.
